WebJan 18, 2024 · Currently, we have torch.randperm to randomly shuffle one axis the same way across all the same way. Perhaps off topic comment: I also wish PyTorch (and NumPy) had a toolkit dedicated to sampling, such as reservoir sampling across minibatches. Sampling often introduces subtle bugs. Additional context. Variations of this feature … WebIn this paper, we propose an efficient Shuffle Attention (SA) module to address this issue, which adopts Shuffle Units to combine two types of attention mechanisms effectively. Specifically, SA first groups channel dimensions into multiple sub-features before processing them in parallel. Then, for each sub-feature, SA utilizes a Shuffle Unit to ...
