Synchronized-batchnorm

WebSome researchers have proposed a specific synchronizing technique for batch normalization to utilize the whole batch instead of a sub-batch. They state: Standard Implementations of BN in public frameworks (suck as Caffe, MXNet, Torch, TF, PyTorch) are unsynchronized, which means that the data are normalized within each GPU. WebJun 30, 2024 · Below, in (1) we explicit the batch norm output as a function of its input. (2) Locally, we can define the input of BatchNorm as a product between the convolution weights and the previous activations, with an added bias. We can thus express in (3) the BatchNorm output as a function of the convolution input which we can factor as equation (4 ...
