FID compares multivariate Gaussian statistics derived from deep neural network features rather than raw pixels.
Fréchet Inception Distance, or FID, is a statistical metric used to evaluate generative image quality by comparing feature distributions of generated images to real datasets. Stable Diffusion’s performance was benchmarked against earlier GANs and diffusion models using FID scores. Lower scores indicate closer alignment with real-world image distributions. While FID does not capture aesthetic preference fully, it provides a standardized quantitative comparison. Researchers rely on such metrics to track improvements across versions. Measurement grounds innovation in evidence. Statistics frame progress.
