Abstract

The paper presents a new approach to automatic constructing and training Radial Basis Function (RBF) neural networks based on Differential Evolution (DE) algorithm. The method, called Differential Evolution-Radial Basis Function Network (DE-RBFN) is tested on approximation tasks of exemplary one- and two- dimensional Gaussian functions. Experiments are performed in Matlab environment. The results show that application of DE-RBFN enables to obtain optimal sparse network architecture by tuning the position and width of each basis function. The performance of the method is better than other related procedures applied to RBF networks.
