| Abstract: | It is difficult for BP network to determine the number of input layer's nodes as dealing with the deformation data of single time series.In order to solve this problem,the G-P algorithm is used to calculate the correlation dimension.Taking the embedding dimension m as the best model dimension and reconstructing an equivalent phase-space according to the theory of reconstruction so as to provide a reasonable input for BP network.Considering the influence of dynamical factor of deformation as well as the diff... |
