WebNov 22, 2024 · Pytorch layer norm states mean and std calculated over last D dimensions. Based on this as I expect for (batch_size, seq_size, embedding_dim) here calculation should be over (seq_size, embedding_dim) for layer norm as last 2 dimensions excluding batch dim. WebIn the dropout paper figure 3b, the dropout factor/probability matrix r (l) for hidden layer l is applied to it on y (l), where y (l) is the result after applying activation function f. So in summary, the order of using batch normalization and dropout is: -> CONV/FC -> BatchNorm -> ReLu (or other activation) -> Dropout -> CONV/FC ->. Share.

But yes, I feed a single batch (the same batch) through a batchnorm layer in train mode until the mean of batchnorm layer becomes fixed, and then switch to eval mode and apply on the same batch and I get different results from the train mode, even though the reported batchnorm running mean for both the train …
