人工神经网络就是模拟人思维的第二种方式。这是一个非线性动力学系统，其特色在于信息的分布式存储和并行协同处理。虽然单个神经元的结构极其简单，功能有限，但大量神经元构成的网络系统所能实现的行为却是极其丰富多彩的。-Artificial neural network is the second way to simulate human thinking. This is a nonlinear dynamical system, which feature information distributed storage and parallel co-processing. Although the structure of individual neurons is extremely simple, limited functionality, but the large number of neurons form a network system can realize the behavior is extremely colorful.
