Abstract

Recently, the polynomial echo state network (PESN) has been proposed to incorporate the high order information of input features. However, there are some redundant inputs in PESN, which results in high computational cost. To solve this problem, a backward learning algorithm is designed for PESN, which is denoted as BL-PESN for short. The criterion for input features removing is designed to prune the insignificant input features one by one. The simulation results illustrate that the proposed approach has better prediction accuracy and less testing time than other ESNs.
