### 🚀 The feature
For each classification datasets with balanced distribution on the classes (MNIST, CIFAR-N, etc...), it would be very useful to provide a standard dataset for the imbalanced versi…

Dear Mr. Wang,
Hope this issue find you well.
May I ask for a issue for the training process? How to solve the imbalance of categories in the training data set? I'm failed. the positive class an…
