Persistence Forcing: Exploiting Feature Specialization in Pixel-Space Diffusion

Paper: arXiv:2609.36014
Project Page: chongwang1024.github.io/PerF
Code Repository: github.com/ChongWang1024/PerF

PerF exploits the persistent–active feature organization that emerges under heterogeneous refinement. Persistent-to-Active Conditioning lets persistent features guide active refinement, while Persistence Guidance strengthens their contribution during sampling.
