Determining the structures and parameters of radial basis function neural networks using improved genetic algorithms

Abstract

The method of determining the structures and parameters of radial basis function neural networks (RBFNNs) using improved genetic algorithms is proposed. Akaike’s information criterion (AIC) with generalization error term is used as the best criterion of optimizing the structures and parameters of networks. It is shown from the simulation results that the method not only improves the approximation and generalization capability of RBFNNs, but also obtain the optimal or suboptimal structures of networks.
