tf.contrib.rnn.HighwayWrapper

RNNCell wrapper that adds highway connection on cell input and output.

Based on:

R. K. Srivastava, K. Greff, and J. Schmidhuber, "Highway networks", arXiv preprint arXiv:1505.00387, 2015. https://arxiv.org/abs/1505.00387

Args
cell	An instance of RNNCell.
couple_carry_transform_gates	boolean, should the Carry and Transform gate be coupled.
carry_bias_init	float, carry gates bias initialization.

Attributes
graph	DEPRECATED FUNCTION
output_size	Integer or TensorShape: size of outputs produced by this cell.
scope_name
state_size	size(s) of state(s) used by this cell. It can be represented by an Integer, a TensorShape or a tuple of Integers or TensorShapes.

get_initial_state(
    inputs=None, batch_size=None, dtype=None
)

zero_state

View source

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, 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, s] for each s in state_size.
