Cosine similarity

[llyyyll]

Thanks for your great work. I would like to ask what part of the code the cosine similarity calculation is specifically embodied in?

Hi! You can check https://github.com/Herschel555/CAML/blob/master/code/utils/correlation.py#L24, which is a conventional way to achieve similarity calculation.

Thank you for your answer. I have one more question, in the

CAML/code/train_caml.py

Line 260 in b635479

loss_o = torch.sum(torch.sum(-corr_a * torch.log(corr_v + 1e-8), dim=1)) / num_samples

, why do you do logarithmic operations on corr_v instead of corr_a when calculating cross-entropy

Thank you!

It can be seen that we choose corr_a as the label to supervise corr_v as the prediction.
