Hi, I have a question about calculating an Accuracy in training mode of SimCLR model. How is it working, or how is it possible, that you can compute accuracy when you are training on data without labels? Thanks a lot!

I think it's the accuracy of correctly matching the augmented pairs of the same input sample, as contrastive loss is crossentropy.

Hello, does someone has a reference to where this accuracy metric comes from? I have read the simCLR paper and haven't found it. Is it something the author of this repository came up with?
