说明：  LSTM(Long Short-Term Memory)是长短期记忆网络，是一种时间递归神经网络，适合于处理和预测时间序列中间隔和延迟相对较长的重要事件。
(LSTM (long short term memory) is a long-term and short-term memory network. It is a kind of time recurrent neural network. It is suitable for processing and predicting important events with relatively long interval and delay in time series.)
