WebNov 25, 2024 · To the best of my understanding group norm during inference = 1) normalization with learned mean/std + 2) a learned affine transformed. I only see the parameters of the affine transform. Is there a way to get to the mean/std and change it. WebFusing adjacent convolution and batch norm layers together is typically an inference-time optimization to improve run-time. It is usually achieved by eliminating the batch norm layer entirely and updating the weight and bias of the preceding convolution [0]. However, this technique is not applicable for training models.

WebDec 4, 2024 · BatchNorm impacts network training in a fundamental way: it makes the landscape of the corresponding optimization problem be significantly more smooth. This ensures, in particular, that the gradients are more predictive and thus allow for use of larger range of learning rates and faster network convergence.
