Lastly, as a tip, ditch LSTMs for IndRNNs; where former struggles w/ 800-1000 timesteps, latter's shown to succeed w/ 5000+. Features are also more interpretable, as each channel is independent, absent LSTM-type gating mechanisms. Web. Web. Feature selection is a way of selecting the subset of the most relevant features from the original features set by removing the redundant, irrelevant, or noisy features. While developing the machine learning model, only a few variables in the dataset are useful for building the model, and the rest features are either redundant or irrelevant. LSTMs have three types of gates: input gates, forget gates, and output gates that control the flow of information. The hidden layer output of LSTM includes the hidden state and the memory cell internal state. Only the hidden state is passed into the output layer while the memory cell internal state is entirely internal.
