神经网络是单个并行处理元素的集合，我们从生物学神经系统得到启发。在自然界，网络络功能主要由神经节决定，我们可以通过改变连接点的权重来训练神经网络完成特定的功能

-The neural network is a collection of a single parallel processing elements, we are inspired by biological nervous system. In nature, the network network function is determined by the ganglion, we can change the connection point of the right to re-train the neural network to perform the specific function
