Args | |
---|---|
num_units
|
int, The number of units in the Phased LSTM cell. |
use_peepholes
|
bool, set True to enable peephole connections. |
leak
|
float or scalar float Tensor with value in [0, 1]. Leak applied during training. |
ratio_on
|
float or scalar float Tensor with value in [0, 1]. Ratio of the period during which the gates are open. |
trainable_ratio_on
|
bool, weather ratio_on is trainable. |
period_init_min
|
float or scalar float Tensor. With value > 0. Minimum value of the initialized period. The period values are initialized by drawing from the distribution: e^U(log(period_init_min), log(period_init_max)) Where U(.,.) is the uniform distribution. |
period_init_max
|
float or scalar float Tensor. With value > period_init_min. Maximum value of the initialized period. |
reuse
|
(optional) Python boolean describing whether to reuse variables
in an existing scope. If not True , and the existing scope already has
the given variables, an error is raised.

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. |
Methods
get_initial_state
get_initial_state(
inputs=None, batch_size=None, dtype=None
)
zero_state
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.
