I am going through the following blog on LSTM neural network:http://machinelearningmastery.com/understanding-stateful-lstm-recurrent-neural-networks-python-keras/ The author reshapes the input vector X as [samples, time steps, features] for different

众所周知,LSTM的一大优势就是其能够处理变长序列.而在使用keras搭建模型时,如果直接使用LSTM层作为网络输入的第一层,需要指定输入的大小.如果需要使用变长序列,那么,只需要在LSTM层前加一个Masking层,或者embedding层即可. from keras.layers import Masking, Embedding from keras.layers import LSTM model = Sequential() model.add(Masking(mask_value=
