tf.keras.initializers.Identity

Initializer that generates the identity matrix.

Inherits From: Initializer

Also available via the shortcut function tf.keras.initializers.identity.

Only usable for generating 2D matrices.

Examples:

# Standalone usage:
initializer = tf.keras.initializers.Identity()
values = initializer(shape=(2, 2))
# Usage in a Keras layer:
initializer = tf.keras.initializers.Identity()
layer = tf.keras.layers.Dense(3, kernel_initializer=initializer)

gain Multiplicative factor to apply to the identity matrix.

Methods

from_config

View source

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.
