【Abstract】 This paper discusses fault saturation in the studing process of BP network,and presents an improved algorithm which can avoid saturation. The simulation results prove that the algorithm can not only complete the study process quickly, but also avoid local minimum in studying process of neural network. So the algorithm can also improve the precision of the neural network and the generalization capability.更多还原
