Medium and long-term forecast method of regional economic development level based on echo state network

Abstract

In order to improve the medium and long-term forecast effect of regional economic development level, this paper combines the echo state network (TESN) to construct a medium and long-term forecast model for regional economic development level. Through the structural characteristics of the deep echo state network and the update criterion of the reserve pool (TRP), this paper improves the deep echo state network, and proposes the deep echo state network on the basis of TESN, and improves the single hidden layer structure of TESN. The improved deep echo state network only collects the state of TRP connected to the output layer, thereby reducing the size of the state matrix of TRP. The experimental study shows that the medium and long-term forecast effect of the regional economic level proposed in this paper is good.
