tf.keras.layers.ELU

Exponential Linear Unit.

Inherits From: Layer, Module

It follows:

    f(x) =  alpha * (exp(x) - 1.) for x < 0
    f(x) = x for x >= 0

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.

Same shape as the input.

alpha Scale for the negative factor.
