function leakyReLU(args) {
	  return new LeakyReLU(args);
	}
Leaky version of a rectified linear unit.

It allows a small gradient when the unit is not active:
`f(x) = alpha * x for x < 0.`
`f(x) = x for x >= 0.`

Input shape:
  Arbitrary. Use the configuration `inputShape` when using this layer as the
  first layer in a model.

Output shape:
  Same shape as the input.
