arXiv:2602.09651v2 Announce Type: replace-cross Abstract: Diffusion models do not recover semantic structure uniformly over time. Instead, samples transition from semantic ambiguity to class commitment within a narrow regime. Recent theoretical work attributes this transition to dynamical instabilities along class-separating directions, but practical methods to detect and exploit these windows in trained models are still limited. We show that tracking the class-conditional entropy of a latent semantic variable given the noisy state provides a reliable signature of these transition regimes. By
This paper leverages recent theoretical work on dynamical instabilities in diffusion models to propose a practical method for understanding class commitment, building on the rapid advancements in AI research.
A strategic reader should care because improving the understanding and control of diffusion model behavior, particularly regarding semantic structure, directly impacts the efficiency, safety, and reliability of generated AI content and applications.
The ability to reliably track class-conditional entropy provides a new way to detect crucial transition regimes in diffusion models, potentially leading to more controllable and predictable AI generation processes.
