Where the Score Lives: What Wavelets Reveal About Diffusion Models
A wavelet-based interpretable parameterization of the score function reveals that local interactions most strongly impact denoising performance, and wavelets yield greater gains at higher resolutions; this framework serves as a theoretical probe—not a replacement—for trained models.
