| Abstract: | On the basis of integrating the wavelet de noising, the theory of phase space reconstruction and LS SVM, a modeling and forecasting technique is put forward. First, the wavelet de noising is used to pre process data, then the best embedding dimension and time delay of nonlinear deformation data are calculated with the method called “C C”, the phase space is reconstructed as well. At last, the modeling prediction is carried out by LS SVM and also is compared with BP neural network. The results show that the prediction model of chaotic time series based on wavelet de noising and LS SVM is better. |
