tf.compat.v1.nn.rnn_cell.RNNCell

Abstract object representing an RNN cell.

Inherits From: Layer

Every RNNCell must have the properties below and implement call with the signature (output, next_state) = call(input, state). The optional third input argument, scope, is allowed for backwards compatibility purposes; but should be left off for new subclasses.

This definition of cell differs from the definition used in the literature. In the literature, 'cell' refers to an object with a single scalar output. This definition refers to a horizontal array of such units.

An RNN cell, in the most abstract setting, is anything that has a state and performs some operation that takes a matrix of inputs. This operation results in an output matrix with self.output_size columns. If self.state_size is an integer, this operation also results in a new state matrix with self.state_size columns. If self.state_size is a (possibly nested tuple of) TensorShape object(s), then it should return a matching structure of Tensors having shape [batch_size].concatenate(s) for each s in self.batch_size.

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.
