长短期记忆网络（LSTM，Long Short-Term Memory）是一种时间循环神经网络，是为了解决一般的RNN（循环神经网络）存在的长期依赖问题而专门设计出来的，所有的RNN都具有一种重复神经网络模块的链式形式。在标准RNN中，这个重复的结构模块只有一个非常简单的结构，例如一个tanh层。(LSTM (Long Term short-term Memory) is a kind of time circulation neural network, which is specially designed to solve the long-term dependence problem of general RNN. All RNN have a chain form of repeating neural network modules.
In the standard RNN, this repeating structure module has a very simple structure, such as a tanh layer.)
