How Diffusion Models Decide on Image Classes

In this AI Research Roundup episode, Alex discusses the paper: 'The Entropic Signature of Class Speciation in Diffusion Models' This research investigates how diffusion models transition from semantic ambiguity to specific class commitment during the generation process. The authors introduce a method to track class-conditional entropy to identify the precise noise regimes where these semantic decisions occur. By analyzing this entropy, the study reveals the exact moments when models like Stable Diffusion 1.5 establish their final structure. The framework also provides a principled way to quantify how guidance techniques redistribute semantic information over time. These insights offer a new foundation for time-localized control in image generation models.
