tf.keras.layers.ELU
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.
