Pulse coupled neural network (PCNN) has a specific feature that the fire of one neuron ca pture its adjacent neurons to fire due to their spatial proximity and intensity similarity. In this paper, it is indicated that this feature itself is a ver

神经网络BP算法，学习规则是使用最速下降法，通过反向传播来不断调整网络的权值和阈值，使网络的误差平方和最小-Neural network BP algorithm, learning rule is to use the steepest descent method, by back propagation to constantly adjust the network weights and threshold, minimize the error sum of squares of t

If a neuron receives a stimulus in its resting state its membrane potential is mainly charged by the stimulus directly At the same time(SCM complies with the mechanism of relative and absolute refractory periods of a real neuron When the neural me
