Why is the output of a linear layer different when the batch size is …

WebBecause the Batch Normalization is done over the C dimension, computing statistics on (N, L) slices, it’s common terminology to call this Temporal Batch Normalization. Parameters: num_features ( int) – number of features or channels C C of the input eps ( float) – a value added to the denominator for numerical stability. Default: 1e-5 WebAug 20, 2024 · I know the different is really small numerically, but it is strange to me that when the batch size is 1 (in the last line, the size of the input is [1, 4] whereas the top line is [16, 4] ), the representation seems to be different. Why is this happening? Is it possible that this could actually affect the model performance?
