Pytorch reweight

WebUnofficial PyTorch implementation of Learning to Reweight Examples for Robust Deep Learning. The paper addresses the problem of imbalanced and noisy datasets by learning a good weighting of examples using a small clean and balanced dataset. Please Let me know if there are any bugs in my code. Thank you! =) WebWeight normalization is a reparameterization that decouples the magnitude of a weight tensor from its direction. This replaces the parameter specified by name (e.g. 'weight') …
