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 is an algorithm mathematical model that mimics the behavior characteristics of animal neural network and distributive parallel information processing. This network relies on the complexity of the system to achieve the purpose of processing information by adjusting the interconnected relationships among a large number of internal nodes, and has the ability to learn and adapt itself.)
