This paper is concerned with the stability analysis problem for uncertain stochastic discrete-time
recurrent neural networks with time-varying delay. By using linear matrix inequality method and discrete
Jensen inequality, a new Lyapunov–Krasovskii function is established to derive sufficient condition
for globally asymptotical stability in mean square of the recurrent neural networks with stochastic
disturbance. As an extension, we further consider the stability analysis problem for the same class of
neural networks but with uncertainty. It is shown that the newly obtained result is less conservative than
the existing ones when the described system is without disturbance and uncertainty. Meanwhile, the
computational complexity is reduced since less variable is involved. Two numerical examples are presented
to illustrate the effectiveness and the benefits of the proposed method.
