New FD-loss technique improves autoregressive image generation quality

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new post-training technique called Fréchet Distributional Post-Training (FD-loss) for autoregressive image generators. This method addresses the mismatch between token-level cross-entropy pre-training and the distributional quality evaluation of generated images. By using representation-space Fréchet distance as the sole objective, FD-loss adapts pretrained discrete generators. This approach has shown significant improvements, reducing FID and FD_r6 scores by an average of 41.4% and 52.0% respectively across various configurations and datasets. AI

IMPACT Introduces a novel post-training method that significantly enhances the quality of generated images by addressing objective mismatches in autoregressive models.

    Beyond Token-Level Cross-Entropy: Fr\'echet Distributional Post-Training for Autoregressive Image Generation

    arXiv:2608.00562v1 Announce Type: new Abstract: Autoregressive image generators are commonly pretrained with token-level cross-entropy under teacher forcing, yet evaluated by the distributional quality of decoded images. This creates an objective mismatch, because categorical err…
