【Abstract】 Aimed at the shortcoming of the traditional BP algorithm,such as the slow training speed,easy to be trapped into the local optimums,etc,a method to design the multi-layer feed-forward neural network based on immune genetic algorithm is proposed.In order to solve the problem of the random initial weights,the strategy of simulated annealing for diversity based on immunity is used to initialize the weight vectors.The simulation results show that the proposed algorithm displays a better performance than the hybrid genetic algorithm does.更多还原
