人工神经网络（Artificial Neural Networks，简写为ANNs）也简称为神经网络（NNs）或称作连接模型（Connection Model）。它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。

Data Normalization for Neural Networks A Beginner's Guide
数据归一化将数据映射到[0,1]或[-1,1]或其他区间。为什么归一化？ 1. 输入数据单位不一样，有些数据的范围特别大，导致神经网络收敛慢，训练时间长。 2. 数据范围大的输入在模式分类中的作用可能偏大，范围小的作用可能偏小。 3. 由于输出层激活函数的值域有限制，需将数据映射到激活函数的值域。
