Pytorch weighted sampler
http://www.sacheart.com/ WebNov 24, 2024 · The general idea is that you first need to create a WeightedRandomSampler object, passing in a weight vector and optional parameters. Then, you can call the sample () method on this object to generate random samples. The PyTorch WeightedRandomSampler can be used to calculate skewed datasets.
