Apply a multi-layer Elman RNN. [Elman, 1990].

Examples:

m = torch.nn.RNN(32, 64)
x = torch.ones(8, 32, 256)
outputs, hidden = m(x)

Create a RNN module.

Parameters:
  • input_size (int) – The dimension of input.
  • hidden_size (int) – The dimension of hidden state.
  • nonlinearity ({'tanh', 'relu'}, optional) – The nonlinearity.
  • num_layers (int, optional, default=1) – The number of recurrent layers.
  • bias (bool, optional, default=True) – True to use bias.
  • batch_first (bool, optional, default=False) – True to use order [N, T, C] otherwise [T, N, C].
  • dropout (number, optional, default=0) – The dropout ratio.
  • bidirectional (bool, optional, default=False) – Whether to create a bidirectional rnn.
