Initializer that generates tensors with a uniform distribution.

Inherits From: Initializer

Used in the notebooks

Used in the tutorials

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


# Standalone usage:
initializer = tf.keras.initializers.RandomUniform(minval=0., maxval=1.)
values = initializer(shape=(2, 2))
# Usage in a Keras layer:
initializer = tf.keras.initializers.RandomUniform(minval=0., maxval=1.)
layer = tf.keras.layers.Dense(3, kernel_initializer=initializer)

minval A python scalar or a scalar tensor. Lower bound of the range of random values to generate (inclusive).
maxval A python scalar or a scalar tensor. Upper bound of the range of random values to generate (exclusive).
seed A Python integer. Used to create random seeds. See tf.compat.v1.set_random_seed for behavior. Note that seeded initializer will not produce same random values across multiple calls, but multiple initializers will produce same sequence when constructed with same seed value.



View source

Instantiates an initializer from a configuration dictionary.


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

config A Python dictionary, the output of get_config.

A tf.keras.initializers.Initializer instance.

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

A JSON-serializable Python dict.


View source

Returns a tensor object initialized as specified by the initializer.

shape Shape of the tensor.
dtype Optional dtype of the tensor. Only floating point and integer types are supported. If not specified, tf.keras.backend.floatx() is used, which default to float32 unless you configured it otherwise (via tf.keras.backend.set_floatx(float_dtype)).
**kwargs Additional keyword arguments.
