tfmri.initializers.HeUniform
tfmri.initializers.HeUniform¶
- class HeUniform(seed=None)[source]¶
Bases:
keras.initializers.initializers_v2.HeUniform
He uniform variance scaling initializer.
Note
This initializer can be used as a drop-in replacement for tf.keras.initializers.HeUniform. However, this one also supports initialization of complex-valued weights. Simply pass
dtype='complex64'
ordtype='complex128'
to its__call__
method.Also available via the shortcut function
tf.keras.initializers.he_uniform
.Draws samples from a uniform distribution within
[-limit, limit]
, wherelimit = sqrt(6 / fan_in)
(fan_in
is the number of input units in the weight tensor).Examples:
>>> # Standalone usage: >>> initializer = tf.keras.initializers.HeUniform() >>> values = initializer(shape=(2, 2))
>>> # Usage in a Keras layer: >>> initializer = tf.keras.initializers.HeUniform() >>> layer = tf.keras.layers.Dense(3, kernel_initializer=initializer)
- Args:
- seed: A Python integer. Used to make the behavior of the initializer
deterministic. Note that a seeded initializer will not produce the same random values across multiple calls, but multiple initializers will produce the same sequence when constructed with the same seed value.
