Covariance-aware sampling for Diffusion Models

stat.ML · 2026-05-13 · conditional · novelty 7.0

A covariance-aware extension of DDIM sampling for pixel-space diffusion models that uses Tweedie's formula and Fourier decomposition to model reverse-process covariance and improves sample quality at low NFE.

  • Spectral Tail Auxiliary Learning for AI-Generated Image Detection cs.CV · 2026-05-21 · unverdicted · none · ref 1

    STAL transfers spectral tail uplift cues via a frequency teacher to train a spatial detector for AI-generated images, discarding frequency modules at inference for strong cross-generator generalization.
