However, the consistency of the benefit across tasks is presently unclear. I am having problems installing keras. We also saw an improved version of the ReLu function. What we are doing is a write a wrapper function called my_activation which will return a Leaky ReLu with negative slope of 0.3 if the parameter is LeakyReLU else it will return the normal activation . We can get an idea of the relationship between inputs and outputs of the function by plotting a series of inputs and the calculated outputs. This type of activation function is popular in tasks where we may suffer from sparse gradients, for example training generative adversarial networks.
