WebNote that other implementations of layer normalization may choose to define gamma and beta over a separate set of axes from the axes being normalized across. For example, Group Normalization (Wu et al. 2024) with group size of 1 corresponds to a Layer Normalization that normalizes across height, width, and channel and has gamma and …
