摘要
介绍了BP网络结构的重要性 ,总结了设计BP网时确定隐含层层数及其节点数的几种传统方法及一种新方法 ,此方法将矩阵分解理论引入BP网络结构优化中 ,为其指出了一个全新的思路及未来的发展趋势 .
In this paper the importance of back propagation net wo rk structure is introduced. At the same time ,several traditional methods and a new way to choose the number of the hidden layers and its nodes number when we design the back propagation network are summed up, the new method involves the theory of matrix decomposition in optimizing the structure of back propagation network , and the author points out a overall new thought way, prospects the dev elopment trend in the future.
