محدودیت و دوره ای برای خطای آستانه خطی زمان گسسته شبکه عصبی با چهار بعدی با تاخیر زمانی

In this paper, the discrete-time quaternion-valued neural network with linear threshold activation functions is investigated. The sufficient conditions to the boundedness and global exponential periodicity of the neural network are obtained by using characteristic equation, Lyapunov functional and M-matrix. Simulation results illustrative the effectiveness of the conclusions obtained in this paper.
