tf.initializers.identity

Class identity

Inherits From: Initializer

Aliases:

  • Class tf.initializers.identity
  • Class tf.keras.initializers.Identity

Defined in tensorflow/python/ops/init_ops.py.

Initializer that generates the identity matrix.

Only use for 2D matrices.

Args:

  • gain: Multiplicative factor to apply to the identity matrix.
  • dtype: The type of the output.

Methods

__init__

__init__(
    gain=1.0,
    dtype=tf.float32
)

Initialize self. See help(type(self)) for accurate signature.

__call__

__call__(
    shape,
    dtype=None,
    partition_info=None
)

Call self as a function.

from_config

from_config(
    cls,
    config
)

Instantiates an initializer from a configuration dictionary.

Example:

initializer = RandomUniform(-1, 1)
config = initializer.get_config()
initializer = RandomUniform.from_config(config)

Args:

  • config: A Python dictionary. It will typically be the output of get_config.

Returns:

An Initializer instance.

get_config

get_config()

Returns the configuration of the initializer as a JSON-serializable dict.

Returns:

A JSON-serializable Python dict.
