中文说明：
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。如人脑的某一部分进行机械记忆特别有效而某一部分进行抽象思维特别有效。
English Description：
Neural network is a collection of single parallel processing elements, which is inspired by biological nervous system. In nature, the function of network is mainly determined by ganglion. We can train neural network to complete specific functions by changing the weight of connection points. For example, a part of the human brain is particularly effective for mechanical memory, while a part of the human brain is particularly effective for abstract thinking
