摘要

The introduction of the full paper points out that the prediction model based on ESN (echo state network) proposed by H. Jaeger in Ref. 1 is, in our opinion, not good enough. So we propose what we believe to be a new and better prediction model based on ESN and PCA (principal component analysis). Section 1 briefs the relevant information in Refs. 2 through 6. Section 2 explains our prediction model; its block diagram is given in Fig. 2. Section 3 gives eq. (6) for measuring the prediction precision of our prediction model. Section 4 compares the simulation results of our prediction model with those of the prediction model based on ESN. The simulation results, given in Figs. 4 through 7 and in Tables 1, 2 and 3, and their analysis show preliminarily that: (1) the computing complexity of our prediction model is lower; (2) its training time is shorter; (3)the prediction rate is higher than that of the prediction model based on ESN.
