提出一个被常数刺激驱动的耦合神经网络模型 ,在这个网络的参数空间中能出现具有分形结构的阶梯 .讨论发现这阶梯是一临界边界 .跨越它 ,系统的其中一层网络的总活性从部分兴奋向完全兴奋过度 .数值计算分析了这阶梯具有分形结构的原因
A coupled neural network model driven by constant stimuli is proposed, in which the ladder with fractal structure can be found in the parameter space of this network. The discussion shows that this ladder is a critical boundary. Across it, the total activity of one layer of the network in the system changes from the part Excitement to complete excitement. Numerical analysis of the ladder has a fractal structure of the reasons
