Title: Stability of neural networks
Abstract: 
In this talk, the problem of stability analysis for neural Networks are studied in this paper. In order to handle this issue, an appropriate Lyapunov-Krasovskii functional (LKF) is constructed and by employing obtained multiple integral inequality, some sufficient conditions are derived in terms of simplified linear matrix inequalities (LMIs), whose Matlab LMI toolbox makes it easy to demonstrate feasible solutions. Finally, numerical examples are given to validate the efficiency of the obtained results.
