WebWhile it can in principle be done, there are now multiple normalization layers that do not have this issue: LayerNorm, InstanceNorm and their generalization GroupNorm are all privacy-safe since they don't have this property.We offer utilities to automatically replace BatchNorms to GroupNorms and we will release pretrained models to help transition, … WebLayerNorm can be applied to Recurrent layers without any modifications. Since it normalizes over all dimensions except the batch dimension, LayerNorm is the method …
