When n_y is large, it seems that the loss weights α are always equal to 1. If so, CB Loss makes no sense. @richardaecn
For example, 10,000 images belong to class A, and only 1,000 images belong to class B. Then the CB weights are [1,1], no matter how much β is.
Please correct me if I have any misunderstanding. Thanks.

I make a mistake that I only try [0.1, 0.2, ..., 0.9]. When β is extremely large like 0.9999, it is different.
