Submodular functions characterize the diminishing returns effect and are widely applied in many fields such as economics, combinatorial optimization, information theory, and machine learning. Hence, research on submodular functions attracts significant attention. In recent years, the scale of problems that need to be addressed has gradually increased with the advancement of computer science. Moreover, the functions that need to be optimized in real-world scenarios often exhibit properties similar to submodular functions but do not strictly conform to the definition of submodular functions. Therefore, designing fast algorithms for set functions that are close to submodular properties has become a research focus. For the problem of optimizing monotone non-submodular functions subject to matroid constraints subject to matroid constraints, with a Diminishing-Return (DR) ratio of γ , this paper presents the γ-MatroidContinuousGreedy Algorithm (γ-MCG Algorithm). This algorithm is a nearly-linear time approximation algorithm with an approximation ratio of (γ²(1 − 1/𝑒)² − O(ϵ)). Notably, it is the first known nearly-linear time algorithm for graph matroid constraints and partition matroid constraints.

This paper studies the power transmission network planning problem using a hybrid GRASP algorithm, which combines the advantages of the Greedy Randomized Adaptive Search Procedure (GRASP) and the Simulated Annealing (SA) algorithm. By incorporating the Metropolis sampling criterion of the SA algorithm, the hybrid GRASP algorithm can probabilistically accept inferior solutions during the local search phase, effectively enhancing the algorithm's ability to escape local optima. We validate the correctness and superiority of this hybrid algorithm through simulation experiments on an 18-node system. The experimental results show that the hybrid GRASP algorithm not only optimizes computational efficiency but also significantly enhances the algorithm's convergence performance. Additionally, this study explores key parameters affecting algorithm performance, such as the number of feasible solutions constructed, temperature regulation, and the setting of the Restricted Candidate List (RCL) percentage, providing more efficient and feasible optimization strategies for power transmission network planning. The results of this study have significant theoretical and practical value for guiding the optimization design and operation of actual power transmission networks.

In response to the drawbacks of traditional genetic algorithms, such as premature convergence, low optimization efficiency, and inadequate precision, improvements have been made to traditional genetic algorithms from two aspects: calibration of the fitness function and diversification of the population. This has prevented traditional genetic algorithms from prematurely converging to local optimal solutions and broadened the optimization space. The improved genetic algorithm has been applied to architectural structural optimization design by establishing an optimization mathematical model with the objective of minimizing mass, addressing discrete variable structural optimization problems with stress and cross-sectional size constraints. Comparative optimization design results have been conducted between the improved genetic algorithm and standard genetic algorithms. The results indicate that the evolutionary generations of the improved genetic algorithm are fewer than those of the standard genetic algorithm, with significantly better convergence performance. This has enhanced the computational speed and optimization effectiveness of genetic algorithms in structural optimization applications.

When evaluating the degree of air pollution, the PM2.5 index is often regarded as an important assessment indicator. The ability to accurately predict the future PM2.5 air pollution index at a certain time based on past data has significant research implications in areas such as public health protection and adjustments to production and economic activities. Based on this, a network model combining LSTM and ridge regression was proposed for predicting the air pollution index. Initially, operations such as handling missing data, preprocessing, data scaling, and standardizing data steps were carried out on the dataset to ensure better convergence during training of the neural network. It was observed that with an increase in the number of training epochs, overfitting occurred, leading to an increase in mean squared error. The use of ridge regression to assist in predicting with the LSTM model yielded better results. Emphasis was placed on the feature values of the air pollution index, with the feature values of the LSTM training model being extracted and used as input for the ridge regression model, resulting in improvements in the prediction errors (MSE, MAE, and SMAPE). This confirmed the high level of fitting of the model on the designated test set and actual data. Furthermore, it was found during the experimental process that in the absence of other auxiliary feature values (such as temperature, humidity, and precipitation conditions), more accurate results could be obtained by using ridge regression to assist the LSTM model.

In the traditional civil aviation transportation industry, airlines have limited means of obtaining aircraft operational data, lack algorithm models that match the health status, and lack application of analysis of fault modes and impacts of key aircraft systems, as well as solutions to fault problems, which prevents a comprehensive understanding of the aircraft's health status and prediction of health trends. To reduce the operational risks of civil aircraft, this study analyzes the current research status of civil aircraft operational risks and proposes a single-aircraft risk assessment method that combines the Fault Mode and Effect Analysis (FMEA) with Fault Tree Analysis (FTA) for individual aircraft. For the fleet, the study first estimates the exposure frequency of risks using historical operational data of civil aircraft through maintenance planning; then, it establishes risk calculation models and an uncensored fleet risk analysis method based on the Weibull bathtub curve's random failure period and wear-out failure period, and uses actual examples to obtain the fleet's risk change trend and the faced risk values. By analyzing and summarizing the above methods, three improvement directions for reducing operational risks are proposed, effectively reducing the operational risks of civil aircraft.

This article considers the point estimations and interval estimations for a generally inverse exponential distribution on the basis of the progressive first failure censoring. We derive the maximum likelihood estimators along with corresponding asymptotic confidence interval at first. Next, we compute the maximum likelihood through the utilization of the Expectation Maximization (EM) algorithm. Afterwards, Bayesian inference is applied using both symmetric and asymmetric loss functions in scenarios involving either informative or non-informative priors. The M-H algorithm is utilized to compute point estimation, which leads to the highest posterior density credible intervals simultaneously. Eventually, a numerical simulation test is executed for the sake of evaluating the qualities of estimations mentioned and authentic dataset is investigated.

The strategic synchronization of multiple reservoir operations for flood management is a vital non-engineering strategy that enhances the flood mitigation capabilities of these reservoirs. It can enhance reservoirs' flood control ability, and play a role in regulating flood peak, saving flood, alleviating or even avoiding flood disaster. This paper takes the three large reservoirs of Chushandian, Nanwan and Suyahu above Wangjiaba in the main stream of the Huaihe River as examples, takes the floods in July 2020 as the input, changes their previous independent and regularized operation mode, and aims to minimize the sum of the maximum flood control storage capacity occupied by the three reservoirs as the target for joint optimal operation of reservoir group flood control under the premise of ensuring downstream flood control safety. The corresponding model is established and solved by improved PSO. The results show that the improved PSO algorithm has higher search efficiency and convergence accuracy. Compared with regular scheduling, optimal scheduling can ensure the safety of the reservoir and downstream control stations in the basin, and the total storage capacity occupied by the three reservoirs can be reduced by 123 million m³.

The conventional hyperchaos security encryption algorithm for power big data center users' personal privacy information mainly uses Lorenz average index pre-diction center for random encryption coding, which is vulnerable to the exponential divergence of initial parameters, resulting in low encryption performance indicators.

Although search recommendation algorithms have been widely used, they also face a large bottleneck: it is difficult to improve recommendation accuracy and reduce user cost-effectiveness. Leaderboards adopts the popular goods priority recommendation strategy, without considering the user behavior data in the decision-making process, as well as differentiation factors between users make recommendations less effective, which in turn affects the conversion rate. Therefore, this paper proposes a personalized recommendation algorithm framework based on the B2C list, on the one hand, by considering the consumer user's current behavioral data to carry out the development trend of predictive recommendation, on the other hand, by information such as the average price and quantity of each major category of goods purchased by the consumer to categorize users, and then combined with the user's preference for the cross-information on the commodity to carry out the differentiation of commodity recommendation, so as to formulate a popular commodities list. The proposed framework has been analyzed and validated through legal advice website data to ensure its feasibility, but further analysis and research is needed due to the large number of B2C industry categories and the complexity of the data.

The technique of measuring blood pressure (BP) through photoplethysmographic (PPG) signals has been widely applied. But this category of methods faces challenges such as the complexity of measurement devices, cumbersome feature selection and inadequate performance.

Furthermore, the method complies with standards set by the Association for the Advancement of Medical Instrumentation (AAMI) and the British Hypertension Society (BHS), indicating its reliability and practicality in clinical applications. In conclusion, the MSCBU-Net model presents an effective BP measurement method with broad prospects for application in the medical field.

With the development and widespread application of industrial information technology, greenhouse cultivation techniques have seen extensive use in agricultural production. Traditional manually managed greenhouses employ rudimentary methods, relying heavily on manual irrigation and temperature regulation. Effectively predicting the tomato greenhouse environment has emerged as a key research challenge. Accurate forecasting of future greenhouse conditions aids cultivators in efficient regulation, saving both time and labor management costs. Therefore, in this paper, to predict future environmental temperatures effectively, we propose a Time Multi Branch Attention Model (TMBAM). This model extracts strongly correlated factors of environmental temperature, captures the importance of various related features, and performs feature extraction for time series characteristics to predict environmental temperature and humidity. By comparing common algorithms such as LSTM, GRU, and other machine learning methods, our model demonstrates improved performance on evaluation metrics like MSE, MAE, and MAPE, showcasing excellent predictive capabilities.

This paper aims to extract keyframes and stage division of sports diving competition videos by advanced image processing and clustering algorithms to improve the efficiency of video analysis. Firstly, we cut the sports competition video into a series of images, store them in a folder, and perform Gaussian filtering and grayscale preprocessing. Then, a two-dimensional similarity matrix is constructed by comparing the Euclidean distance similarity of each frame with all other images in the cut order using a Siamese network. The positive characterization of the properties of the matrix is discussed in depth, which lays a theoretical foundation for the subsequent clustering analysis. An improved Jenks Natural Breaks clustering algorithm is used in the study to minimize intraclass variance and maximize inter-class separation. To optimize the clustering effect, this paper designs a new objective function, E, whose core idea is the exponent of the negative of the sum of interclass variance and intraclass variance. By comparing the values of E, we find the four-class clustering results that make the value of E more minor and thus identify the three keyframes in the video. These keyframes divide the video into four stages, effectively placing the change points between stages. Despite the interference of noisy points, the researcher further optimized the results through mean filtering processing. Ultimately, this approach improves video processing efficiency and lays the foundation for subsequent video evaluation and analysis through key frame extraction and stage division.

Wordle, a popular daily puzzle offered by The New York Times, challenges users to guess a five-letter word within six attempts, with feedback provided through a color-coded system. This study explores the dynamic patterns of player engagement and result reporting on social media platforms such as Twitter, where users frequently post their game outcomes. The primary aim of our research is to understand and predict the variations in the distribution of these reports using a robust modeling approach that incorporates elements from epidemiological modeling. To address the fluctuations in reporting frequency and simulate the influences of game mechanics on player behavior, we employed the SIR (Susceptible, Infected, Recovered) model, commonly used to describe the spread of infectious diseases. This model helped us to conceptualize the spread of player engagement as analogous to an infectious disease, where interest peaks and then diminishes over time. Our adapted "Zombie Model" further refined this approach by including categories such as susceptible humans, infected zombies, and recovered individuals, along with a novel category of 'serum carriers' who exhibit mild infections and recover quickly, offering a nuanced understanding of the engagement lifecycle. Through rigorous data normalization and analysis, we observed patterns consistent with infectious disease spread—a sharp rise in activity followed by a gradual decline. The results from the model not only provided insights into how game design and external factors such as social media influence player interactions but also predicted future trends in player engagement. Our findings contribute to the broader understanding of digital media interaction and can inform future game design to enhance user engagement and retention.

With the increasing awareness of privacy protection, federated learning is increasingly applied to distributed training scenarios. However, in the process of executing federated learning on distributed clients, due to the non-independent and identical distribution between clients, the accuracy and convergence speed of the global model will decrease in the model aggregation process of ordinary federated learning. To solve this problem, a federated learning framework is proposed to improve the model aggregation method. During training, the server extracts the feature parameters of the local model, and performs entropy regularization on each layer of the local model to obtain the optimal transmission feature parameters. Finally, the optimal transmission and other federated learning global model feature parameters are generated by fusion. In the distributed training of the two data sets, the data distribution in four different cases was simulated for federated training comparison. The results show that compared with ordinary federated learning, the proposed algorithm significantly improves the model performance and the convergence speed of the global model, which can be used for distributed user training and commercial privacy-sensitive scenarios.

Aiming at the problems of poor visualization effect of recovered image, not rich in image details, too dark and unnatural image, etc., which exist in the dark channel a priori algorithm to deal with the large sky area, a dark channel a priori adaptive image defogging algorithm based on the RGB channel and the Retinex reflectance map is proposed. To address the issue where the restored image appears overly dark and lacks the clarity needed to reveal fine details, the pixel values of the three RGB channels of the original image are calculated and added to the original atmospheric light values to obtain an adaptive function to correct the brightness values. The reflection map in the Retinex algorithm is used to calculate the reflection component of the original image, and then the Gaussian filter is used to estimate the light component of the original image, and the transmittance is obtained by using these two components. The experimental results show that the proposed algorithm can effectively recover the detail information of the foggy image, the defogging is more thorough, the overall smoothness, the color brightness is better, the image is clear and natural, and the computational speed is ahead of the existing algorithms.

In this paper, an improved hybrid algorithm based on particle swarm optimization (PSO) and genetic algorithm (GA) is formed to solve the problem of "premature" and slow convergence.

The mixed coding method of traditional coding and binary coding is used to solve the problem of uncertain number of unmanned aerial vehicles (UAVs). At the same time, the PSO algorithm is reduced by increasing the inertia weight, increasing the time-varying factor, and adopting the adaptive mutation probability, bit mutation and cross mutation methods for GA to increase the convergence speed and global search ability of the hybrid algorithm. Finally, the overall cost of the improved hybrid algorithm, hybrid algorithm and traditional algorithm is compared by simulation, and the effectiveness and accuracy of the proposed algorithm are verified.

The seaplane motion signal has strong nonlinearity, and it is difficult to make accurate predictions by traditional forecasting methods. For this reason, this paper proposes to use the combination of EMD and CNN-GRU to forecast two different motions of seaplane based on in-depth research on EMD and neural networks. Firstly, EMD is used to decompose the original non-smooth signal into smoother modal components, and then the CNN network, which has the strong ability to extract non-linear features, is combined with GRU, which has the function of long-term memory, and the CNN-GRU parallel neural network model is used to train each component, which improves the forecasting accuracy and reduces the complexity at the same time. Through comparison experiments with the CNN-GRU model, a single CNN model, and a single GRU model, the effectiveness of the proposed hybrid model in short-term forecasting is verified, which expands a new idea for the research of seaplane motion forecasting methods.

In recent years, deep neural networks have made significant advancements, surpassing traditional models in computer vision. However, the vast number of parameters in deep models poses challenges such as increased network size, sluggish computation, high computational costs, and extensive storage requirements, thus hindering deployment on resource-constrained platforms like mobile devices. This paper focuses on compressing convolutional neural networks to address these challenges. This paper proposes a structured pruning method that integrates MobileNet features to prune the MobileNetV3-Large model, resulting in a more compact and efficient model. The approach involves sparse regularization training to obtain a sparser network model, which is followed up by structured pruning. This pruning is performed by leveraging the product of the sparsity values of convolutional layers and the scaling factors of batch normalization layers to identify and remove redundant filters. Experiments were conducted on the CIFAR-10 dataset. The experimental results demonstrate that the proposed compression method effectively reduces model parameters, decreases model size, minimizes runtime memory usage, and diminishes computational operations, while maintaining comparable performance levels despite the compression. Specifically, for MobileNetV3-Large, the model's parameter count is reduced by 40%, and computational operations are reduced by 35%, all while maintaining the same level of accuracy.

This article analyzes the current research status of multi-agent reinforcement learning from the perspective of the training architecture and reward allocation of multi-agent reinforcement learning. From the analysis of the interaction process between fully cooperative multi-agent and environment, it can be seen that the focus is on solving the problem of reward allocation. However, common methods have problems such as low training efficiency, insufficient collaboration ability between multi-agent systems, and inability to adapt to large-scale scenarios. Therefore, this article proposes a collaborative multi-agent reinforcement learning method based on reward adaptive allocation, lists specific steps, and according to the analysis of experimental results, it can be concluded that this method can achieve higher and less volatile environmental rewards compared to MADDPG. Therefore, this method can explore samples more efficiently and improve training efficiency through the guidance of reward functions. In addition, the constraints of reward functions can enhance the stability of decision-making.

Artificial Intelligence (AI) has made remarkable advancements, surpassing human capabilities in various domains. This paper delves into cutting-edge AI technologies, analyzing significant models and techniques. However, current AI models have not fully captured the essence of human instincts, which we believe to be the core differentiator between humans and machines. We further explored simple human instinctive behaviors using a cellular automata (CA) model. While CA successfully emulated basic instincts, it fell short in replicating complex instinctive behaviors. We propose that future collaborations between computer science researchers and neuroscientists could offer the potential for gaining deeper insights into the underlying mechanisms of human instincts, developing advanced “artificial instinct” technology and producing the next generation of revolutionary machine systems.

Information extraction is a fundamental aspect of natural language understanding tasks. Previous works generally utilized a transformer-based architecture as a text encoder. However, gradient vanishing and attention dispersion tend to be inevitable when tacking document-level paragraph texts, which have negative effects on capturing global token relationships. To address these limitations, we propose CDM-IE, an information extraction approach specifically designed for lengthy text input. The CDM-IE is a hybrid CNN-Transformer architecture with dual-branch topology, respectively named a paragraph encoding branch and a dependence mining branch, which excels at learning comprehensive text representation by integrating both global context and local dependence. The two pathways converge at a dependence-guided attention module, which acts as a fusion bridge to feature alignment and synergy. Ablative experiment results on the Medical Entity Extraction (CCKS 2019) and Chinese Machine Reading Comprehension (CMRC 2018) datasets indicate that the proposed CDM-IE showcases improved performance and robustness on information extraction tasks, which provide a valuable solution for text modeling on long sequences.

Reversible information hiding in the encrypted domain has been utilized in numerous programs as it enables the embedding of secret information within the encrypted data while safeguarding the image content. Owing to its significance in the realm of privacy, this technology has garnered substantial attention and undergone significant development. Distinct from the traditional end-to-end reversible information hiding in the encrypted domain, the reversible information hiding scheme based on secret sharing is more applicable to applications in the cloud environment due to its multi-party security and fault tolerance. This paper undertakes a review of the development progress of Reversible information hiding based on secret sharing and conducts an analysis of the characteristics of existing schemes.

Aiming at the problem of high number of sensor nodes in the existing Data Link system and the inefficiency of message delivery, collection and processing within the sensor network, this paper proposed a message processing model based on improved TEEN routing protocol (MPMIT). Using the improved TEEN routing protocol in the sensor network, the message delivery path is determined by selecting cluster head nodes to form clusters. After the message is delivered to the sink node, the target trajectory data within the message is parsed, and the trajectory data is fused by the FCM clustering algorithm. The experimental results in the simulation environment showed that the target trajectory formed by the MPMIT model processing had a higher degree of coincidence with the actual trajectory, and the effect is better, which can effectively solve the message processing problem of sensor nodes in the Data Link system.

Medical image translation can provide auxiliary diagnosis for medical treatment, and existing methods are mostly based on GAN models. However, GAN models have limitations in learning image detail information, and therefore face many challenges. We mainly propose a new model for unpaired medical image translation based on wavelet transform and UNIT, WaveUNIT. This model decomposes the input image into low-frequency and high-frequency images through wavelet transform, and then inputs them into the low-frequency and high frequency generation parts of the generator, respectively. Finally, the obtained image is subjected to inverse wavelet transform to obtain a translated image. The cyclic network structure allows our model to be used for unpaired medical image translation tasks, and the additional high-frequency image loss constraint further enhances our model’s learning and extraction of high frequency image detail information. On this basis, we validated the effectiveness of WaveUNIT through experiments on different medical image translation datasets. We demonstrated the quality of generated images and the stability of the model from multiple dimensions, including quantitative analysis of performance indicators and qualitative analysis of visualization results. Finally, ablation experiments also demonstrated the superiority of the proposed method in unpaired medical image translation tasks.

Usually, mutation strategies and the corresponding parameter values play an important role in DE. Because different mutation strategies reveal different characteristic during the course of the evolution, combing different mutation strategies has been one of the research direction for DE improvement.

Furthermore, the candidate pool of eD-MPEDE contains three novel mutation strategies with different characteristics, which help to balance exploratory and convergence. Tests on CEC2017 show that eD-MPEDE is efficient to obtain promising solutions.

To address this issue, an adaptive differential evolution algorithm with accompanying population (APADE) using differential evolution (DE) meta-heuristic optimization algorithm as the basic framework is proposed. The Largest-Order-Value (LOV) transform the newly generated vectors in the population into discrete ordered permutation vectors using the concept of discretization to make the APADE applicable to discrete coded. The initial set values of mutation factor and crossover rate are reset with the size of the PFSP to address the problem that improper settings of these two parameters can lead to the optimization search process falling into local optimums prematurely or the exploration phase being too extended. Each generation of successful control parameters are positioned in the historical memory, and this effective parameter adaptation technique guides the future control parameter values in the direction of advantageous evolution. In addition, a two-stage accompanying population is designed to slow down the rate of convergence and to enrich the diversity of the population at the later stages of the iteration. Finally, experiments comparing APADE with three other improved metaheuristics on 23 benchmark instances verify the performance of the APADE.

Named Entity Recognition (NER) is a critical task in Natural Language Processing (NLP). Compared to English NER, Chinese NER faces several issues due to differences in grammar between Chinese and English, which affect the performance of Chinese NER models. The current mainstream solution is to innovate lexical information into character-level models to achieve lexical enhancement. However, this process can introduce incorrect or irrelevant lexical information, leading to conflicts between words and affecting entity boundary segmentation and category annotation. To address this issue, this paper proposes a multi-feature fusion model based on Transformer. Building on the original model, which uses character vectors and word vectors as feature inputs, we add a new type of feature input: vectors obtained by re-weighting different words through adjusting lexical weights. This approach reduces the impact of incorrect lexical information, thereby enhancing model performance. Experiments on multiple datasets demonstrate the effectiveness of this method.

We study the decision-making problems encountered by two agents in parallel allocation and introduce the concept of risk attitudes. Risk attitudes reflect the likelihood of success in a competitive parallel allocation scenario. The probability of success is zero for risk-averse individuals, whereas it is certain for risk-seeking individuals. Individuals with different risk attitudes can accordingly adjust their strategies. When both agents are risk-averse, we provide the strategic characteristics that satisfy the Subgame Perfect Nash Equilibrium (SPNE) and design an algorithm to find the SPNE strategies. We prove the algorithm's correctness and resolve the selection conflict issues caused by even and odd items. When both agents are risk-seeking, we similarly provide the strategic characteristics that satisfy the SPNE and design an algorithm to find the SPNE strategies. Finally, we present a strategic analysis demonstrating the non-existence of relevant SPNE when one agent is risk-seeking and the other is risk-averse.

Sleep staging is a complex process that necessitates precise and robust analysis of polysomnographic signals. In this study, we introduce a novel approach aimed at effectively extracting crucial information from both the time and frequency domains of the signal. Our method is composed of three primary components: a multi-head spatiotemporal attention mechanism, and a module for multi-task learning. The spatiotemporal attention mechanism concurrently concentrates on various spatial locations and frequency ranges of the signal, enhancing the model’s attention allocation efficiency and precision. The multi-task learning-based module effectively leverages the correlation between sleep stages and can perform sleep staging and transition tasks simultaneously, thereby boosting the model’s learning capability and adaptability. The hyperparameter optimization method, which is based on the loss function, strikes a balance between the significance of the primary and secondary tasks to achieve optimal learning outcomes. By conducting a comprehensive analysis of various modules and hyperparameters, we examined the model’s performance and influencing factors, and validated the model’s rationality and robustness. The findings of this study offer significant support and direction for the ongoing advancement of sleep staging tasks.

In order to solve the problem that the traditional airborne radar multi-target tracking data association algorithm needs to obtain the prior information such as clutter density and target motion model in advance, a multitarget-tracking algorithm about data association based on Mamba network is constructed. The proposed algorithm combines the efficiency of selective state space and hardware-aware algorithms. This paper uses a data-driven approach to learn the mapping relationship between each target and measurement without providing various prior information to solve the problem of associating multiple targets with multiple measurements, and comprehensively considers the problems of missed detection and false alarm. Simulation results show that the optimal sub-pattern assignment (OSPA) distance error of the proposed algorithm is smaller, and it has better performance than the algorithm based on the Bi-LSTM network and the classic data association algorithm in the tracking experiment.

To address the challenges of occlusion in intelligent picking within unstructured environments, this paper proposes an occlusion perception algorithm utilizing knowledge distillation. A grape occlusion dataset was developed to support the study. The proposed method employs a lightweight MobileNetV3 student model, trained under the supervision of a high-accuracy ResNet50 teacher model, to achieve comparable performance with significantly fewer network parameters. Experimental results demonstrate that the knowledge-distilled student model operates with only 1.50% of the teacher model's operations while achieving an accuracy of 99.4%, representing a 2.4% improvement over the baseline model. These findings underscore the method's effectiveness in developing efficient, high-performance models suitable for deployment in resource-constrained environments.

Entity linking, the task of associating named entities mentioned in the text with their corresponding entries in a knowledge graph, addresses the inherent ambiguity in entity mentions. This process enhances semantic comprehension in both knowledge graph integration and natural language processing tasks. To address inefficiencies in processing lengthy texts and understanding complex contexts in existing models, this study proposes an innovative model, AT-LOM. The model integrates Longformer pre-training techniques and adversarial training mechanisms into text encoding, employs Extrapolatable Position Embedding (xPos) in the entity detection module and utilizes beam search algorithms in the linking module to rank text sequences generated by Long Short-Term Memory (LSTM). The AT-LOM model demonstrates significant performance enhancements on the standard AIDA-CoNLL dataset, achieving a 1.0% to 13.1% increase in Micro-F1 values compared to mainstream methods in recent years.

Word embedding is a widely used method for representing words in contemporary natural language processing, where words are depicted as low-dimensional dense vectors. However, the features of each dimension in the vector are difficult to interpret. Most existing interpretable word embedding methods enhance the interpretability of word embeddings through orthogonal or sparse transformations. Still, the semantics of each dimension need to be determined according to the knowledge base or manually assigned after transformation. Embedded topic model (ETM) can automatically acquire interpretable semantic space of words, but this topic space tends to be ambiguous and redundant. To address this issue, this paper proposes an Explainable Text Representation method with a Learnable and Explicit Semantic Space (ETRLESS), which autonomously learns an orthogonal explicit semantic space, allowing words and documents to be represented as interpretable vectors within this space. It obtains the document embedding representation through a BiLSTM model, initializes topic embeddings through pre-training ETM model, and imposes orthogonal constraints on the topic embedding to obtain a more interpretable topic semantic space. By using the reconstruction loss of documents, the document-topic distribution loss, and the orthogonal loss of topic embeddings as optimization objectives, it employs the backpropagation algorithm to learn an interpretable, orthogonal explicit topic semantic space and word representations based on this space. The results demonstrate that the embeddings generated by the ETRLESS model have clear semantic information in each dimension and maintain performance in downstream tasks.

Bare soil will cause the soil erosion and contribute to air pollution through the generation of dust, making timely and effective monitoring of bare soil an urgent requirement for environmental management. Though there have been some researches in bare soil extraction using high-resolution remote sensing images, great challenges still need to be solved, such as complex background interference and multi-scale problem. In this regard, the Hybrid Attention Network (HA-Net) is proposed for automatic extraction of bare soil from high-resolution remote sensing images, which includes the encoder and the decoder. In the encoder, HA-Net initially utilizes BoTNet50 for primary feature extraction, producing four-level features. The extracted highest-level features are then input into the constructed Spatial Information Perception Module (SIPM) and the Channel Information Enhancement Module (CIEM), to emphasize the spatial and channel dimensions of bare soil information adequately. During the decoder, the Semantic Restructuring-based Upsampling Module (SRUM) is proposed to leverage the semantic information of input features, and compensate for the loss of detailed information during the down-sampling in the encoder. Experiment is performed based on high-resolution remote sensing images from the China-Pakistan Resources Satellite 04A. The results show that HA-Net obviously outperforms several excellent semantic segmentation networks in bare soil extraction. The IoU and Recall of HA-Net in test scene can reach 81.4% and 87.4%, respectively, which demonstrates the excellent performance of HA-Net. It embodies the powerful ability of HA-Net for suppressing the interference from complex background and solving the multi-scale issue.

The anchor-based iterative deep graph representation learning (IDGL-anchor) method has the potential to yield excellent performance in node classification. Nevertheless, IDGL-anchor demonstrates simplicity when it comes to the selection of anchor points and overlooks the significance of these points. Additionally, throughout the learning process, it solely employs labeled nodes to direct the learning objectives, disregarding the information provided by unlabeled nodes and thereby squandering the valuable unlabeled information. To tackle these problems, a centrality-guided deep dynamic graph clustering (CGDDGC) method has been proposed. It enhances the strategy for choosing anchor points through the utilization of a centrality metric function. An unsupervised clustering module is incorporated to leverage unlabeled information for guiding the learning process. Simultaneously, the model is optimized by taking into account both labeled and unlabeled nodes, enhancing the accuracy and efficiency of node classification. Experiments conducted on five benchmark datasets demonstrate that our method surpasses IDGL-anchor and other state-of-the-art approaches.

The flight test data recorded in the airborne test are removed after the test and sent to the data unloading room for unloading. In order to improve the efficiency of flight test, it is necessary to achieve the level of quasi real-time processing, and get the processing results within 1~2 hours after the test. It is necessary to consider greatly shortening the time of data unloading and processing. By laser communication technology airborne record system test data cache to airborne laser communication terminal. Before aircraft landing, air-borne data is transferred to the ground laser communication terminal with the speed of 10Gbps, so that test data has been processed before aircraft landing, that save from waiting for landing to download the data a large segment time, significantly improve data produced speed and finally improve test efficiency.

Text-to-SQL is an important research direction in the field of artificial intelligence. This paper introduces a novel Text-to-SQL application framework based on large language models (LLMs), aiming to achieve more accurate Text-to-SQL generation. We propose three methods to effectively leverage the synergy between LLMs and Text-to-SQL prompts. Firstly, we employ prompt words in JSON format that include database query examples. Through interaction with LLMs, accurate SQL statements can be generated. Secondly, we utilize the Chain of Thought (CoT) prompt word method, prompting the model with query tables, fields, and conditions to generate SQL statements that comply with grammar rules. Finally, we enhance Text-to-SQL inference accuracy by querying an SQL knowledge base. We con- duct experiments on the Spider benchmark, which consists of 20 databases and 1034 query statements. The experimental results demonstrate that, under the single-domain database condition, the CreateTable+SelectCol+Normalized method achieves a Text- to-SQL accuracy of 77.9 with a 16-shot setting. This represents a 1.4% improvement compared to the Codex baseline.

This paper proposes a defense framework against jailbreak attacks that exploit multi-language and multi-intent inputs. Research indicates these attacks are effective primarily due to two reasons: (1) LLMs may incorrectly capture key points and semantics in low-resource language inputs, generating malicious content; (2) multiple requests within a single input can cause attention flickering, leading to inadequate capture of implicit requests and incorrect responses. The proposed defense framework requires no additional training and works by mapping multi-language inputs to high-resource languages, guiding the model to think multiple times, decompose intents, and reflect. Experimental results show significant effectiveness of this framework in defending against attacks.

Traditional graphite ore production typically relies on carbon-sulfur analyzers to determine the carbon grade of graphite ore. This method, however, is cumbersome and lacks timeliness. To address these issues, we propose TRA-FFNet, a graphite carbon grade image recognition and classification model that integrates multi-level features from ResNet and Transformer. Initially, ResNet-50 is employed as the backbone feature extraction network, with model parameters initialized through transfer learning to accelerate convergence. Subsequently, a Transformer module based on spatial feature compression fusion is designed to capture the weight relation-ships among different channels of the graphite ore feature map. Finally, a multi-level feature fusion module is incorporated at the network's terminal position to enhance the joint learning of both global and local features in graphite ore images. Experimental results show that the pro-posed model achieves an accuracy of 93.473% and an F1 score of 94.023% on our self-constructed dataset containing 19 classes of graphite ore, outperforming classic models such as MobileNetv2, EfficientNet-b3, ConvNext, RepVgg, and Swin Transformer. The proposed model achieves high-precision recognition of graphite ore grade in an end-to-end manner, offering a valuable detection solution for smart mining operations.

Artificial Intelligence (AI)-based Internet of Things (IoT) applications benefit greatly from advanced deep learning models. However, the increasing complexity and resource requirements of deep learning models pose challenges to computational efficiency and deployment on resource-constrained devices. To address these challenges, the paper proposes a merging technique to efficiently merge multiple single-task deep learning models into a unified multi-task model. The proposed method merges models in a serial fashion, potentially replacing various layers with a smaller deep neural sub-network to connect the layers of the previous model and the latter model's layers. This method improves computational efficiency, and can create larger models to perform the functions of the original models with minimal training overhead. The paper designs and implements a merging model that supports end-to-end compressed sensing (CS) sampling and object detection, and the experimental results verify the efficacy of the proposed method in generating fine-tuned multi-task deep neural models with minimal training time and resource costs, making it a cost - efficient solution for edge-cloud collaborative inference.

Infrared technology plays a crucial role in various fields. However, defocus blur occurs in infrared images due to improper focusing, resulting in undesirable blurring effects. In recent years, deep learning-based methods have achieved remarkable success in image restoration. However, the spatial variability of defocus blur, combined with the low resolution and lack of textural details in infrared images, still presents significant challenges for deblurring. In this paper, we propose a CNN-based neural network that employs dynamic large separate kernel convolutions to adapt to real-world defocus blur patterns and to effectively extract blur features. Furthermore, we introduce an encoder-decoder feature fusion module that incorporates edge attention, spatial attention, and channel attention to enhance the network’s focus on edges while selectively processing relevant information, thereby improving the network’s deblurring performance. Experimental results demonstrate that our method outperforms recent advanced methods in handling defocus blur in infrared images. Additionally, ablation studies are provided to show the effectiveness of the proposed modules.

Through this contribution, we aim to propel the advancement of cloud segmentation techniques, facilitating improved data accuracy for a broader spectrum of geospatial and atmospheric studies.

Slurm is a resource management and job scheduling system widely used in the field of parallel computing. Kubernetes is an open source container orchestration platform widely used in cloud native and AI fields. With the development of technologies such as parallel computing, AI, and large-scale data processing, the demand for computing resources in business scenarios has become more complex and diverse. In order to better adapt to business needs and give full play to the advantages of both in different fields, this paper proposes a fusion scheduling solution based on Slurm and Kubernetes. The solution is mainly aimed at two scenarios: partitioned deployment and hybrid deployment. The fusion scheduling between the two is realized by developing the heterogeneous resource manager Unify. Dynamic node management function is provided for partitioned deployment, and unified resource view and unified scheduling function are provided for hybrid deployment. Application results show that the solution can effectively solve the problem of dynamic node division under partitioned deployment and the resource scheduling conflict problem of Slurm and Kubernetes under hybrid deployment. Through this solution, both can be applied to more complex demand scenarios and improve the overall resource utilization of the cluster.

Chaotic image encryption technology has become a key method for safeguarding sensitive image data and has garnered significant attention and research recently. To address the issues of limited key space and low encryption efficiency in conventional image encryption methods, this paper introduces a novel chaotic image encryption algorithm. This algorithm leverages Chen and Logistic-Tent chaotic mappings along with dynamic DNA encoding rules. Initially, the SHA-256 algorithm is employed to produce a 256-bit hash sequence, which serves as the initial key for the chaotic mappings. The chaotic sequences generated by these mappings are then used to rearrange the rows and columns of image pixels, while dynamically chosen DNA encoding rules are applied to encode each pixel. Following this, the DNA-encoded image matrix is XORed with the chaotic sequence matrix to produce a scrambled image matrix. In the final step, the encoded ciphertext image is decoded using DNA, and minor plaintext alterations are diffused across the entire ciphertext through multi-level diffusion processes. This approach enhances the complexity and security of the encryption method. Experimental results indicate that the proposed algorithm effectively withstands various types of attacks while maintaining high encryption efficiency, demonstrating promising application potential and practical value.

Finally, the attack research status and implementation performance on both soft/hardware platform of each algorithm are reviewed, and the efficiency of their software and hardware implementation is compared.

Dunhuang culture is a treasure house of human history and culture. As an integral part of Dunhuang culture, Dunhuang dance is famous for its unique national characteristics and artistic characteristics. In the form of Dunhuang dance, instrumental music and props are used to greatly enrich the stage expression, forming a unique dance form of "holding music while dancing, dancing with instruments".

Secondly, based on the recognition of related instruments, a diffusion model instrumental prop image generation that can be used in the Chinese context is trained. Experimental results show that the instrumental props generated by this method not only conform to realistic logic but also have strong applicability.

With the continuous development of Low Earth Orbit (LEO) satellite constellations, their application in the Global Navigation Satellite System (GNSS) has been increasingly emphasized. Minimizing the Geometric Dilution of Precision (GDOP), a key metric for evaluating positioning configurations, along with ensuring a sufficient number of positioning satellites, presents new opportunities and challenges for the selection of GNSS positioning satellites. While additional observation satellites can lower the GDOP value, an excessive number can increase the computational burden on receivers. The recent surge in the number of LEO satellites enhances the potential for GDOP minimization, bringing theoretical optimal spatial distributions within closer reach. In this paper, we address the challenge of GDOP minimization under observation-constrained conditions through a geometric analysis. We first develop a set of nonlinear algebraic equations to determine the conditions for minimized GDOP. These conditions are articulated by segregating satellites into high and low selection regions based on a predefined ratio, ensuring maximal satisfaction of various equation sets within each region. An intelligent optimization algorithm is then crafted to meet this geometric condition, with the concurrent fulfillment of all equation sets as its primary goal. This strategy successfully realizes a GDOP minimization algorithm that is resilient to occlusions. Finally, we assess the positioning performance under a range of occlusion scenarios, as well as with varying numbers and configurations of satellites. The findings offer valuable insights for the enhancement of future satellite positioning systems within expansive LEO satellite constellations.

In conventional single image super-resolution (SISR) models utilizing deep learning, information is generally transmitted in a feedforward fashion. Nonetheless, these models have not fully exploited the feedback mechanism. Drawing inspiration from the feedback process in human vision, we introduce a Multiscale Feature Extraction Feedback Network (MFEFN), which utilizes high-level information to enhance low-level details. In particular, we employ the principles of Recurrent Neural Networks (RNNs) to reintroduce part of the output back into the model as input, thereby optimizing the input feature representations. We design a multiscale feature extraction channel attention feedback module to handle the feedback connections and generate rich detail texture features. Additionally, to address the issue of limited receptive fields and singular convolutional kernels in models, we propose a multiscale feature extraction module to capture detail texture features at different scales. To further enhance the model's cross-channel learning capability, we incorporate a channel attention mechanism. Comprehensive experimental results showcase the proposed MFEFN's superiority over current state-of-the- art methods.

Due to occlusion and other problems during point cloud scanning, the collected point clouds are often incomplete. Therefore, reconstructing a complete point cloud based on a partial point cloud with missing information is of great significance in practical work. In this paper, we propose a point cloud completion method (PointVQDM) based on the VQ-Diffusion model, which uses a discrete diffusion model to model in the latent space for shape reconstruction. Specifically, we obtain the corresponding vector combination based on the partial point cloud, and use the point cloud quantization network to decode it to obtain a complete point cloud. Experimental results on multiple datasets show that our PointVQDM outperforms the most advanced completion network. Moreover, thanks to our feature fusion method, we achieve diverse and high-quality generation results.

As computer systems become increasingly complex, deep learning methods for rapidly analyzing and pinpointing anomalies in system logs are gaining widespread application to ensure smooth system operation. Addressing the issues of many existing methods that require substantial amounts of labeled data and insufficient utilization of temporal features in logs, we propose a semi-supervised log anomaly detection method. Initially, log templates are extracted using the Drain template parsing technique. Subsequently, BERT is employed to extract deep semantic feature vectors from logs and to derive time feature vectors. Unsupervised clustering algorithms are then used to estimate labels for unlabeled samples, tackling the problem of insufficiently annotated data in practical log anomaly detection scenarios. Finally, anomaly detection is achieved using a Attn-based Bi-LSTM model. Experimental results on two datasets, HDFS and BGL, demonstrate that our proposed method achieves notable improvements in terms of accuracy and recall, thereby validating the effectiveness of our work.

Construction projects typically consist of multiple processes. Therefore, process allocation needs to be conducted before project begins. Traditional process allocation requires the construction party to have extensive experience. However, with the rapid development of artificial intelligence, AI-based automated process allocation for construction projects has become possible. In this paper, we identify that the problem of process allocation in construction projects is essentially a partial multi-label recognition problem. To address this issue, we propose an automated process allocation method for construction projects based on partial multi-label recognition. This method contains a label feature decoupling module and a missing label inference module. First, we use a cross-attention mechanism to construct the label feature decoupling module and extract label features from project descriptions. Then, the missing label inference module employs graph convolution networks to capture label correlations and infer missing labels from existing partial labels. We validated the effectiveness of our method by using a private dataset of power construction projects.

As a new type of device discovered in recent years, memristors have many advantages such as non-volatile and multi value storage. With the improvement of research on their preparation, characterization, and testing, memristors have broad application prospects in non-volatile memory, computing/storage fusion architecture computing systems, new neural computing systems, and other fields, and are highly likely to change the physical basis of existing IT technology. Accurate weight control is the key to the application of memristors, but there are still some technical difficulties that are difficult to overcome in current research, such as the incomplete understanding of the conduction mechanism of memristors, the coexistence of multiple conduction mechanisms and their mutual transformation, which to some extent limit the largescale practical application of memristors. Therefore, this article focuses on the characteristics of memristors and designs a gate voltage feedback memristor weight precise control system using Moku: Go, a universal instrument. The system is controlled through a GUI interface and some devices are selected for testing in the prepared TiN/TaOx/HfOx/TiN memristor 1T1R array. The final test results show that the system achieves fast and accurate weight control.

Continuous action segmentation is a challenging task in video semantic understanding, aims to temporally segment unedited long videos. Current state-of-the-art methods combine time-domain convolution with self-attention mechanisms to capture temporal correlations, achieving high-accuracy frame-level classification and reducing over-segmentation during prediction. However, these models rely on multiple decoding modules and complex self-attention mechanisms, which, while improving frame accuracy, incur high computational costs, particularly when dealing with long video sequences. To address this issue, we propose a novel hybrid model that optimizes the temporal convolutional model with a simplified extended linear self-attention layer. This design enables the model to focus more effectively on action changes at key moments in a video sequence while significantly reducing computational complexity. Furthermore, we introduce an attention enhancement module with a pyramidal pooling structure to improve the model's ability to capture actions at multiple scales. By leveraging these innovations, our hybrid model achieves a better balance between accuracy and computational efficiency, making it more suitable for real-world applications involving long video sequences. The experimental results demonstrate that our model achieves an accuracy of 86.0% on the 50Salads dataset and 84.6% on the GTEA dataset, outperforming existing techniques such as MS-TCN++ and ASFormer in terms of both accuracy and computational efficiency. Notably, our model requires only 0.98M parameters, a significant reduction compared to ASFormer's parameter count. These advantages make our model particularly well-suited for practical applications involving long video sequences, where computational efficiency and accuracy are crucial.

Segmentation of medical images is pivotal in the progression of proficient healthcare, especially the segmentation of heart images, which is one of its essential research contents. The U-Net architecture has demonstrated remarkable success across diverse segmentation of medical images tasks. Due to the inherent locality of convolution operations, the classical U-Net architecture exhibits challenges in image segmentation, manifesting as reduced resolution and information loss. Inspired by Transformers, the Vision Transformer model applied to classification tasks has good results. In this paper, a refined medical image segmentation model, HPNet, is proposed, and an encoder module that fuses convolutional network and Transformer structure is designed. The modules are paralleled to extract image features. Can grasp the global and local information of the image wellhouse modules are interconnected in parallel to extract image features, thereby enabling effective capture of both global and local information within the image. In the HPNet model, the encoder structure part of the transformer module and the CNN module are connected in parallel to process the input image. After upsampling the encoded features, the decoder merges them with the high-resolution feature map from the encoder section (the output of CNN and ViT). Secondly, this paper uses pyramid pooling operation in the Transformer module to reduce the complexity of the process and uses Shift MLP to improve the segmentation accuracy. The experimental findings indicate that through reduced computational complexity, the proposed HPNet model can improve the performance of the ACDC heart dataset by 1%.

Parallel programs often struggle to achieve ideal computational speed and parallel efficiency on parallel computers, with communication overhead considered one of the primary limiting factors. However, existing communication performance analysis tools struggle to meet programmers' needs in terms of practicality and efficiency, making it difficult to analyze performance issues. In order to analyze the MPI communication performance of parallel programs more conveniently and comprehensively, a lightweight and low-overhead communication analysis software MPI Toolkit is designed and implemented, which consists of four modules, namely MPI function tracing, MPI function data statistics, log output, and data visualization, and encapsulates MPI functions based on the PMPI analysis interface to intercept MPI function calls, collect communication data during program operation, output it in the form of a log file, and provide a variety of visual views. To evaluate the effectiveness of the MPI Toolkit, comparative experiments between the MPI Toolkit and the TAU performance analysis tool are performed on typical parallel applications HPL and VASP. The results show that the tracing results of MPI Toolkit are basically the same as those of TAU, and the performance overhead is lower, which can easily and efficiently help users to analyze communication performance and locate potential bottlenecks.

Multiple clients can co-train high-performance global models using federated learning (FL) without revealing their personal information. The main obstacle to federated learning, however, is the considerable statistical variability across local data distributions of clients, which results in clients optimizing contradictory local models. We suggest a novel adaptive federated learning method with local drift decoupling and correction (AFEDDC) to tackle this basic problem. We experimentally demonstrate the efficiency, optimality and robustness of AFEDDC and show that AFEDDC outperforms existing algorithms and provides better convergence for FL.

Power grids, as essential infrastructures of modern society, are vital for economic progress and the well-being of the populace due to their stability and reliability. However, the occurrence of natural disasters often leads to severe disruptions in the power grid, causing a sharp increase in material demand. Conventional material allocation models, due to their deficiency in capturing the complex dynamics of long and short-term mixed correlations in time series data, struggle to meet the requirements for rapid and precise material allocation in disaster scenarios.

The experimental outcomes indicate that the DGM-GRU model shows superior performance in both training and validation loss, demonstrating strong generalization capabilities and swift convergence. The model is adept at capturing the trends in material demand, offering scientific decision-making support, and thereby enhancing the efficiency and effectiveness of emergency responses.

Wireless self-powered sensors are necessary for long-term, large-scale, real-time environmental monitoring systems. Triboelectric nanogenerators can capture energy from the environment to power sensors.

FIRE-CLA calculates the fire risks for over 6,000 streets in the city, achieving a prediction accuracy of up to 90%. Additionally, FIRE-CLA presents fire risks at specific locations through an interactive map in a visualized form, making the model more intuitive and practical. This helps firefighting departments enhance their decision-making process for fire inspections.

In network intrusion datasets, the normal traffic is usually magnitude hundreds or even thousands of times more than the minority class attacks, and this dataset imbalance creates greater difficulties in deep learning model training, often leading to the model not being able to effectively learn the data features of the minority class, which in turn reduces the detection efficiency. Therefore, an effective solution is proposed to balance the normal traffic by utilizing WGAN for minority class data augmentation and random undersampling technique for random censoring, aiming to improve the overall model and the detection rate of minority class attacks. Finally, an intrusion detection model based on hybrid neural network for feature extraction is designed to address the shortcomings of existing intrusion detection models in terms of detection capability and structure. In the convolutional part, three different scales of convolutional kernels are used to perform feature extraction on the input data in order to obtain richer feature representations. Meanwhile, a bidirectional long short-term memory (BiLSTM) network is utilized to learn the temporal relationship between features, and a Transformer encoder is introduced to establish the connection between different features.

In complex inspection procedures, there is a significant variation among different personnel. However, the existing personnel scheduling methods often treat individuals as similar or identical entities, which can result in low overall yield and substantial losses for the company. In this context, a study was conducted to improve the yield from the perspective of personnel scheduling in inspections.

This algorithm allows for the selection of suitable personnel from the personnel pool, followed by targeted personnel scheduling based on the defect concentrations specific to each personnel and model. This ensures that the appropriate personnel are assigned to the corresponding models, thereby maximizing the yield for all models. Through experiments and result analysis on different scenarios, as well as comparisons with other algorithms, the test results demonstrate the superiority of this method in terms of convergence and optimization capability. This approach offers a new perspective on scheduling based on the multidimensional testing capability of employees, providing valuable insights for optimizing production and scheduling in enterprises.
