Researchers have developed an information-theoretic approach to understand scaling laws in generative diffusion models. This method, termed 'model information,' quantifies how much a model's outputs depend on its specific training dataset. The study identifies two distinct scaling regimes: a nonlinear regime where memorization transitions to imperfect generalization, and a linear generalization regime with improved sample quality. An information-theoretically principled scaling law is proposed to model these regimes and their induced laws for memorization and sample quality, demonstrating strong extrapolation capabilities. AI
