Need to deal with the major in-balance in the size of the two classes (bga and non_algae).
Below are some good links that describe the importance of making sure the classes are balanced in size an…

first, thank you for this great framework, my question is; what is the best way to define variables for imbalanced classification (with a lot of categories) for which in each batch they might be empty…

Hi, I want to use the `PR-AUC` (or `ROC-AUC`) metrics for a few-shot classification problem where the test data is imbalanced.
Therefore, I need the positive (yes) **probability** to calculate this…
