How to fix the embedding gauge in a BERT-like model?
I have a pre-trained BERT model from Huggingface, which I tune to categorize short texts (like tweets or slightly longer) into several thousand categories using triplet loss.
As I understand, if I ...

Why is the time complexity of the Triplet Loss $O(N^3)$
The triplet loss function uses an anchor, positive, and negative examples. If $N$ are the number of examples in the training set with $C$ classes, then I think that the time complexity should be $O(...
