Activation Function of Wavelet Chaotic Neural Networks

Chaotic neural networks have been proved to be powerful tools for escaping from local minima. In this paper, we first review Chen´s chaotic neural network and then propose a novel chaotic neural network model. Second, we make an analysis of the most positive Lyapunov exponent of the neural units of Chen´s and the proposed model. Third, 10-city traveling salesman problem (TSP) is given to make a comparison between them. Finally we conclude that the novel chaotic neural network model we proposed is more valid.
