ContraGAN (R1, R2, R3, R4), the novelty of the proposed 2C loss (R1, R2, R4), composability with modern

We thank the reviewers for the constructive comments. Every experiment and explanation in this rebuttal will be included in the paper. We will introduce the concept of data-to-data relations carefully. Our 2C loss can take advantage of the strengths of both losses. Compared with Eq. 7 loss, 2C loss considers cosine We conduct experiments to compare 2C loss with other losses.
