A new research paper proposes a re-evaluation of the Fréchet Inception Distance (FID) metric used for assessing image generation quality. The study highlights that FID scores can be misleading, as lower scores do not always correlate with superior sample quality. This discrepancy is partly attributed to the geometric properties of the reference dataset, with concentrated datasets showing more favorable FID trends compared to dispersed ones, even when sample quality improves.
