Adaptive lag synchronization in unknown stochastic chaotic neural networks with discrete and distributed time-varying delays. (English) Zbl 1221.82078

Phys. Lett., A 372, No. 24, 4425-4433 (2008).
Summary: In this Letter, we have dealt with the problem of lag synchronization and parameter identification for a class of chaotic neural networks with stochastic perturbation, which involve both the discrete and distributed time-varying delays. By the adaptive feedback technique, several sufficient conditions have been derived to ensure the synchronization of stochastic chaotic neural networks. Moreover, all the connection weight matrices can be estimated while the lag synchronization is achieved in mean square at the same time. The corresponding simulation results are given to show the effectiveness of the proposed method.
