Class ELU

Exponential Linear Unit.

Inherits From: Layer

Aliases:

  • Class tf.compat.v1.keras.layers.ELU
  • Class tf.compat.v2.keras.layers.ELU

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.

Arguments:

  • alpha: Scale for the negative factor.
