Researchers from USC, CMU, CUHK, and OpenAI have developed a new method called FD-loss that allows the Fréchet Inception Distance (FID) metric to be directly incorporated into the training process of image generation models. This technique decouples the statistical calculations from the gradient updates, enabling smaller models to achieve FID scores below 0.8 on ImageNet. The study also suggests that optimizing solely for FID may not always yield the best visual results, proposing a new metric, FDrk, for more robust evaluation. AI
