Abstract

In the analysis on building deformation, when the deformation is unconscious, the significant effect random noise contributes, in addition that the prediction model of neural network has slow convergence. A new CPSO-LSSVM forecasting model is established, based on the combination of wavelet analysis and Kalman filter. The forecasting model resolves the noise problem and with a high accuracy by improving the PSO algorithm. The results show that it has a higher accuracy than the BP network and the LSSVM.
