Dec 30, 2020 · Batch-normalization and dataset-normalization are two different approaches. The former is a technique that can achieve improved performance in convolution networks. This kind of operation can be implemented using a nn.BatchNorm2d layer and is done using learnable parameters: a scale factor (~ std) and a bias (~ mean).

11.07.2018 · But there is no real standard being followed as to where to add a Batch Norm layer. You can experiment with different settings and you may find different performances for each setting. As far as I know, generally you will find batch norm as part of the feature extraction branch of a network and not in its classification branch(nn.Linear).

How Batch Norm Works. When using batch norm, the mean and standard deviation values are calculated with respect to the batch at the time normalization is applied. This is opposed to the entire dataset, like we saw with dataset normalization. Additionally, there are two learnable parameters that allow the data the data to be scaled and shifted.
