If alpha < 1 (it should be), you can use tf.maximum (x, alpha * x) A leaky relu function has been included with release 1.4.0-rc1 … WebAccording to the authors of the Swish paper, this is what set ReLU apart from the more traditional activation functions. Third, separating Swish from ReLU, the fact that it is a smooth curve means that its output landscape will be smooth. This provides benefits when optimizing the model in terms of convergence towards the minimum loss. cherry 2160704
