Define LSTM model in Flax

We are now ready to define the LSTM model in Flax. To design LSTMs in Flax, we use the LSTMCell or the OptimizedLSTMCell. The OptimizedLSTMCell is the efficient LSTMCell.

The LSTMCell.initialize_carry function is used to initialize the hidden state of the LSTM cell. It expects:

  • A random number.
  • The batch dimensions.
  • The number of units.
