PTL-Diffusion: Manifold-Aware Diffusion with Periodic Terminal Laws
Researchers propose PTL-Diffusion, a novel diffusion model framework that replaces single Gaussian terminal distributions with periodic families of Gaussian laws to better capture manifold structure in data. The approach embeds phase information directly into forward process dynamics rather than only in the denoising network, showing improved performance on point-cloud and facial datasets compared to standard DDPM baselines.
