tf.keras.layers.LeakyReLU

Leaky version of a Rectified Linear Unit activation layer.

Inherits From: Layer, Operation

tf.keras.layers.LeakyReLU(
    negative_slope=0.3, **kwargs
)

Customizing what happens in `fit()`	Deep Convolutional Generative Adversarial Network pix2pix: Image-to-image translation with a conditional GAN

This layer allows a small gradient when the unit is not active.

Formula:

f(x) = alpha * x if x < 0
f(x) = x if x >= 0

Example:

leaky_relu_layer = LeakyReLU(negative_slope=0.5)
input = np.array([-10, -5, 0.0, 5, 10])
result = leaky_relu_layer(input)
# result = [-5. , -2.5,  0. ,  5. , 10.]

Args
negative_slope	Float >= 0.0. Negative slope coefficient. Defaults to 0.3.
**kwargs	Base layer keyword arguments, such as name and dtype.

Attributes
input	Retrieves the input tensor(s) of a symbolic operation. Only returns the tensor(s) corresponding to the first time the operation was called.
output	Retrieves the output tensor(s) of a layer. Only returns the tensor(s) corresponding to the first time the operation was called.

Methods

from_config

View source

@classmethod
from_config(
    config
)

Creates an operation from its config.

This method is the reverse of get_config, capable of instantiating the same operation from the config dictionary.

Note: If you override this method, you might receive a serialized dtype config, which is a dict. You can deserialize it as follows:

if "dtype" in config and isinstance(config["dtype"], dict):
    policy = dtype_policies.deserialize(config["dtype"])

Args
config	A Python dictionary, typically the output of get_config.

Returns
An operation instance.
