Thanks for your attention of HiSD.
The imbalance problem can be widely seen in almost all unpaired datasets in I2I area. In most cases, it would be better if you have balanced dataset. Our dataset is directly converted by the label annotation file of CelebA. Since the labels are unbalanced, the numbers of reorganized images are unbalanced, too. However, if you want to focus on this, the results may be improved if you apply some tricks in long-tailed or unbalanced-labels area.
