Exponential Linear Unit.
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.
