Web28 jun. 2024 · lstm_output: is the h of each time step. So it has shape (batch_size, sequence_length, hidden_size), in your case it is (?, 28, 32). As the documentation says, it is returned as a sequence because you set return_sequences=True. state_h: is the last timestep's h and if you can check, it should be equal to lstm_output [:,-1]. Web1 jun. 2024 · LSTM stands for Long Short-Term Memory. It was conceived by Hochreiter and Schmidhuber in 1997 and has been improved on since by many others. The purpose of an LSTM is time series modelling: if you have an input sequence, you may want to map it to an output sequence, a scalar value, or a class. LSTMs can help you do that.
