"WebLayer normalization is a simpler normalization method that works on a wider range of settings. Layer normalization transforms the inputs to have zero mean and unit variance across the features. Note that batch normalization fixes the zero mean and unit variance for each element. Layer normalization does it for each batch across all elements. " - Layer_norm pytorch
