Moving Mean and Moving Variance In Batch Normalization

WebApr 8, 2024 · BatchNorm 会忽略图像像素（或者特征）之间的绝对差异（因为均值归零，方差归一），而只考虑相对差异，所以在不需要绝对差异的任务中（比如分类），有锦上添花的效果。而对于图像超分辨率这种需要利用绝对差异的任务，BatchNorm 并不适用。 WebApr 21, 2024 · The thing is that in your case, you have a ReLU between the Linear and Batchnorm. So that statement may not be true for your model. I think that statement comes from the fact that the batchnorm will center the values. So a bias is useless in the previous layer as it will just be cancelled by the batchnorm. model2 has much less parameters.
