See the guide: RNN and Cells (contrib) > Core RNN Cell wrappers (RNNCells that wrap other RNNCells)

Operator adding an output projection to the given cell.

Properties

output_size

state_size

Methods

__init__(cell, output_size)

Create a cell with output projection.

Args:

  • cell: an RNNCell, a projection to output_size is added to it.
  • output_size: integer, the size of the output after projection.

Raises:

  • TypeError: if cell is not an RNNCell.
  • ValueError: if output_size is not positive.

zero_state(batch_size, dtype)

Return zero-filled state tensor(s).

Args:

  • batch_size: int, float, or unit Tensor representing the batch size.
  • dtype: the data type to use for the state.

Returns:

If state_size is an int or TensorShape, then the return value is a N-D tensor of shape [batch_size x state_size] filled with zeros.

If state_size is a nested list or tuple, then the return value is a nested list or tuple (of the same structure) of 2-D tensors with the shapes [batch_size x s] for each s in state_size.
