人工神经网络（Artificial Neural Network，即ANN ），是20世纪80 年代以来人工智能领域兴起的研究热点。它从信息处理角度对人脑神经元网络进行抽象， 建立某种简单模型，按不同的连接方式组成不同的网络。神经网络的MATLAB实现(Artificial Neural Network (ANN) is a hot spot in the field of artificial intelligence since 1980s. It abstracts the neural network of human brain from the information processing point of view, establishes a simple model, and forms different networks according to the different connection modes.MATLAB implementation of neural network)
