BP神经网络及其改进

Summarization of BP Neural Network's Improvement

针对标准BP算法存在的缺陷,从网络结构、算法及初始值选取等各个角度系统总结了BP神经网络的各种改进措施,对各种方法的原理及优缺点作了详尽分析,指出了BP神经网络今后改进的方向。

Given that the existing defects of the standard Bp algorithm, this paper summarizes all kind of improvement measures systematically, analyzes the merits and shortcomings of all kinds of methods from the perspectives of BP neural network structure, algorithrm and original values restpectively, thus, pointing out further the direction that BP neural network should improve.
