Web29 nov. 2024 · The keras BatchNormalization layer uses axis=-1 as a default value and states that the feature axis is typically normalized. Why is this the case? I suppose this is surprising because I'm more familiar with using something like StandardScaler, which would be equivalent to using axis=0. This would normalize the features individually.
