WebOct 22, 2024 · PyTorch applies broadcasting, so if alpha is a scalar tensor you could directly run the posted line of code. On the other hand, even if alpha has the shape [batch_size] it should still work (and you might need to unsqueeze () dimensions to enable broadcasting, but it depends on the shapes of the other tensors). 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.
