Abstract:The importance of BP network structure is introduced in the paper,then several traditional methods and a new way about how to choose number of the hidden layers and its nodes when we design BP network are summarized, 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 development trend in the future. At last,the result of applying the theory on the forecast is efficient,the struct...
Keywords:artificial neural networks  Back Propagation network  network structure design  singular value decomposition
