人工神经网络（Artificial Neural Networks，简写为ANNs）是一种模仿动物神经网络行为特征，进行分布式并行信息处理的算法数学模型。这种网络依靠系统的复杂程度，通过调整内部大量节点之间相互连接的关系，从而达到处理信息的目的，并具有自学习和自适应的能力。(Artificial neural network (ANN) is a mathematical model that imitates the behavior characteristics of animal neural networks and carries out distributed parallel information processing. The network relies on the complexity of the system and adjusts the connections between a large number of nodes, so as to achieve the purpose of processing information, and has the ability of self-learning and self adaptation.)
