Web20 aug. 2024 · The rectified linear activation function or ReLU for short is a piecewise linear function that will output the input directly if it is positive, otherwise, it will output zero. It has become the default activation function for many types of neural networks because a model that uses it is easier to train and often achieves better performance. WebLeakyReLU is necessary for skinny network, which is almost impossible to get gradients flowing back with vanilla ReLU. With LeakyReLU, the network can still have gradients even we are in the region where everything is zero out. PReLU - nn.PReLU ()
