"WebBatch Norm has two modes: training and eval mode. In training mode the sample statistics are a function of the inputs. In eval mode, we use the saved running statistics, which are not a function of the inputs. This makes non-training mode’s backward significantly simpler. Below we implement and test only the training mode case. " - Pytorch batchnorm eval
