Why the test accuracy can be higher than train accuracy? #27

Hello,

When I used ModelNet 40 and other dataset to train Point Transformer(Hengshuang), I found after the 3rd epoch, the test accuracy would be higher than train accuracy. It makes no sense a model could perform better when processing unseen data, right? Do you also meet this phenomenon?

This is possible, given that strong data augmentation is used, e.g., random scale, shift, drop (https://github.com/qq456cvb/Point-Transformers/blob/master/train_cls.py#L109).
