摘要
针对一类具M-P型非线性信号传输函数的二元神经网络模型,提出其初值振动时系统周期解的存在性问题。利用结式技巧,结合分析方法,建立了用结式表示的保证具振动初值系统周期解存在的充分条件,并通过例子说明零阈值情形周期解的稳定性。
The existence of the periodic solution for neural networks of two neurons with McCulloch-Pitts type signal functions and oscillatory initial value was proposed. By using the resultant techniques and method of analysis, resultant conditions which ensure the existence of periodic solution of the system with sign change of initial value were established. Furthermore, the stability of the periodic solution of the system with zero threshold was shown by example.
