ASASR — Coloring the Noise: Adversarial Sobolev Alignment for Faithful Image Super-Resolution

Pretrained weights for the ICML 2026 paper Coloring the Noise: Adversarial Sobolev Alignment for Faithful Image Super-Resolution (Hongbo Wang, Huaibo Huang, Pin Wang, Jinhua Hao, Chao Zhou, Ran He).

➡️ Code & full instructions: https://github.com/wafer-bob/ASASR

ASASR performs ×4 image super-resolution with a FLUX.1-dev backbone and dual-LoRA inference: a base SR LoRA (upscaling prior, OminiControl) plus our DPO LoRA trained with a Sobolev frequency-weighted, adversarially-guided DPO objective (AS-DPO).
