Abstract :
In this paper, a novel improved generalized congruence neural networks (NIGCNN) is presented, i.e. generalized piecewise derivative of error function is back propagated to adjust weights of GCNN, which solves the problem that the approximation method, adopted by GCNN and IGCNN, can not control the weight space very well. The results of approximation for sine function and identification simulation for nonlinear dynamical system show that NIGCNN is fully effective. In simulation, NIGCNN´s stability is better than that of the previous two GCNNs, and is almost the same as that of the traditional BPNN, while its convergent speed is faster than that of the traditional BPNN, and is almost the same as that of the previous two GCNNs
