comment: Reviewers agreed that the proposed method is reasonable and intuitive, and that the experiments show a solid improvement. However, there were concerns that the improvements might stem only from using an ensemble of multiple data augmentations, which is not a new idea. There seem to be no ablations done on the optimal transport formulation, which is the other main methodological contribution. Another concern was that the datasets are not very challenging. For example, the optimal transport formulation relies on the classes being balanced, so what happens when this is not true? We encourage the authors to take the reviewers' feedback into account for the camera-ready.
