How to implement the unbiased CL?

[ha-lins]

Hi @chingyaoc,

Thanks for the great work!

I wonder how to implement the method of (supervised) unbiased CL. It could be similar to the work : Supervised Contrastive Learning or just supervised cross-entropy loss. Is my conjecture right? Could you pls share me the script or give some comments about the implementation?

Thanks a lot!
