Mixup data augmentation with Center loss #166

Closed sunilpankaj closed 4 years ago

sunilpankaj commented 4 years ago

I am able to use mixup with cross entropy loss but not sure how it can be applied with center loss and triplet loss also? In paper, mixup augmentation is not mentioned. any reason for not using it?

michuanhaohao commented 4 years ago

Mix augmentation fuses ID labels of two samples. However, both center loss and triplet loss need to be fed into certain ID labels, so mixup augmentation is not suitable for center loss and triplet loss.

Mix augmentation can be applied in triplet loss according to the paper published in icme2021 titled "CUTMIX DUAL BRANCH NETWORK FOR PERSON RE-IDENTIFICATION"
