摘　　要：讨论了误差逆传播算法存在的缺陷 ,并针对其缺陷提出了动态调整学习因子与合理选取激发函数相结合的改进方案。编程验证表明 ,改进后的误差逆传播算法速度快、精度高。Disadvantages of the back propagation algorithm are discussed,and the improved methods based on dynamic learning constants and different activation functions are presented.In order to illustrate the effectiveness of improvement,some experiments are performed and the results indicate that the improved back propagation algorithm has faster speed,higher accuracy and better convergence than the conventional back propagation algorithm.
