Figure 2: (a) Real data covers five modes (1-5) and the generated data is expanded, one mode at a time, to cover the real modes (1-5) and five extraneous modes (6-10). Both metrics were evaluated using 20k real and generated samples. We thank the reviewers for their comments and remarks, and will gladly implement the suggested clarifications. Finally, Figure 1c shows that our metric behaves similarly to FID as the number of samples increases. Furthermore, we thank the reviewer for bringing [2] to our attention, and will cite it as parallel work.
