WebJun 22, 2024 · The ReLU layer is an activation function to define all incoming features to be 0 or greater. When you apply this layer, any number less than 0 is changed to zero, while … WebAug 26, 2024 · For example if you’re using ReLU activation after a layer, you must initialize your weights with Kaiming He initialization and set the biases to zero. (This was introduced in the 2014 ImageNet winning paper from Microsoft ). This ensures the mean and standard deviation of activations of all layers stay close to 0 and 1 respectively.
