WebBecause the BatchNorm is done over the C dimension, computing statistics on (N, H, W) slices, it’s common terminology to call this Spatial BatchNorm. Parameters. num_features – num_features from an expected input of size batch_size x num_features x height x width. eps – a value added to the denominator for numerical stability. Default: 1e-5 Web7. jan 2024 · The picture depicts BatchNorm correctly.. In BatchNorm we compute the mean and variance using the spatial feature maps of the same channel in the whole batch.If you look at the picture that you've attached It may sound confusing because, in that picture, the data is single-channel, which means each grid/matrix represents 1 data sample, however, …
