Abstract: The classical Echo state network (ESN) cannot fully exploit its advantages in some work which characterize strong nonlinearity and high-order statistics. In order to overcome the shortcomings, this paper using the nonlinear readout nodes instead of the traditional linear readout nodes in classical ESN, Radical Basis Function (RBF) neural network was introduced to read out the reservoir state. Benchmark experiments on Lorenz chaotic time series and NARMA model identification shown that the proposed new type of ESN can improve the nonlinear characteristics and it’s performance exceeded the classical ESN in dealing with some higher degree of nonlinear system and model.
