WebNov 6, 2024 · nn.Charles November 4, 2024, 5:55pm #3. Hi @akashgshastri, The fact of applying batch norm before ReLU comes from the initial paper presenting batch normalisation as a way to solve the “Internal Covariate Shift”. The are lots of debate around it and this is still a debate whether or not it should be applied before or after the activation : WebHello all, The original BatchNorm paper prescribes using BN before ReLU. The following is the exact text from the paper. We add the BN transform immediately before the nonlinearity, by normalizing x = Wu+ b. We could have also normalized the layer inputs u, but since u is likely the output of another nonlinearity, the shape of its distribution ...
