[`tf.compat.v1.keras.layers.LeakyReLU`](https://www.tensorflow.org/api_docs/python/tf/keras/layers/LeakyReLU)

<br />

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

It allows a small gradient when the unit is not active:
`f(x) = alpha * x for x < 0`,
`f(x) = x for x >= 0`.

#### Input shape:

Arbitrary. Use the keyword argument `input_shape`
(tuple of integers, does not include the samples axis)
when using this layer as the first layer in a model.

#### Output shape:

Same shape as the input.
