tf.contrib.rnn.OutputProjectionWrapper

class tf.contrib.rnn.core_rnn_cell.OutputProjectionWrapper

Operator adding an output projection to the given cell.

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.
