Initializer that generates an orthogonal matrix.
If the shape of the tensor to initialize is two-dimensional, it is initialized with an orthogonal matrix obtained from the QR decomposition of a matrix of random numbers drawn from a normal distribution. If the matrix has fewer rows than columns then the output will have orthogonal rows. Otherwise, the output will have orthogonal columns.
If the shape of the tensor to initialize is more than two-dimensional,
a matrix of shape
(shape * ... * shape[n - 2], shape[n - 1])
is initialized, where
n is the length of the shape vector.
The matrix is subsequently reshaped to give a tensor of the desired shape.
gain: multiplicative factor to apply to the orthogonal matrix
seed: A Python integer. Used to create random seeds. See
dtype: The data type.
__init__( gain=1.0, seed=None, dtype=tf.float32 )
Initialize self. See help(type(self)) for accurate signature.
__call__( shape, dtype=None, partition_info=None )
Call self as a function.
from_config( cls, config )
Instantiates an initializer from a configuration dictionary.
initializer = RandomUniform(-1, 1) config = initializer.get_config() initializer = RandomUniform.from_config(config)
config: A Python dictionary. It will typically be the output of
An Initializer instance.
Returns the configuration of the initializer as a JSON-serializable dict.
A JSON-serializable Python dict.
