Long-Short Term Memory (LSTM) layer. Corresponds to the LSTM Keras layer .

- Type: Keras Deep Learning NetworkKeras NetworkThe Keras deep learning network to which to add an
`LSTM`layer. The input must have shape [time, features] - Type: PortObjectKeras NetworkAn optional Keras deep learning network providing the first initial state for this
`LSTM`layer. Note that if this port is connected, you also have to connect the second hidden state port. The hidden state must have shape [units], where units must correspond to the number of units this layer uses. - Type: PortObjectKeras Network> An optional Keras deep learning network providing the second initial state for this
