【Abstract】 Chaotic neural network has successfully solved the function optimization and combinatorial optimization problem.This paper presents a new model of chaotic neural network whose activation function is composite of sinusoidal function and Sigmoid function.The reversed bifurcation and the maximum Lyapunov exponent of the chaotic neuron are given and the dynamic system is analyzed,and is used to function optimization and combinational optimization problems.The simulation results show that the searc-optimization capacity of chaotic neural network with sinusoidal Function is improved and the reformative chaotic neural network is superior to the primary chaotic neural networks.更多还原
