Hyperchaos of chaotic neural network
Yang Shu-wen · Journal of Harbin University of Commerce · 2006
Neural network is a kind of highly complex nonlinear dynamic system,and chaotic phenomenon was found in it.By eliminating the simulated annealing mechanism of transiently chaotic neuron,this paper presents a kind of chaotic neuron which can permanently sustain chaotic search.Based on the connection topology of chaotic neural network composed of the four chaotic neurons,the spectra of Lyapunov exponents of chaotic neural network are analyzed,and hyperchaos exists in the chaotic neural network system;meanwhile,the effect of the parameters on the spectra of Lyapunov exponents is researched.
