Exponential Linear Unit.

Inherits From: Layer

tf.keras.layers.ELU(
    alpha=1.0, **kwargs
)

It follows:

  f(x) =  alpha * (exp(x) - 1.) 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.

alpha Scale for the negative factor.
