My contributions to COT-GAN paper (15 June submitted to arXiv) prior to NeurIPS review: * designed all experiments (datasets, baselines and performance metrics); * discovered the bias issue in Section 3.3, contributed to disucssion on mixed-Sinkhorn divergence (eqn 3.7), produced Figure 1 and proved Remark A.3; * carried out all experiments in Section 5.1 and animated action dataset in Section 5.2, produced Figures 2, 3 and 5-8; * substantial paper writing.
