Diffusion models' algorithmic generalization studied via modular arithmetic

By PulseAugur Editorial · [1 sources] ·

Researchers have conducted a mechanistic study on how diffusion models achieve algorithmic generalization, using a modular addition task as a testbed. The study observed that in a single-image scenario, the model encodes operands as periodic representations and combines them at the self-attention--feedforward interface to reconstruct trigonometric addition identities. In a diverse-image scenario, the iterative sampling process separates arithmetic computation from visual refinement, signaled by an internal frequency-entropy metric. AI

IMPACT Provides a mechanistic understanding of how diffusion models generalize, potentially informing future model development and analysis.

    A Mechanistic Study of Algorithmic Generalization in Diffusion Models on Modular Arithmetic

    arXiv:2604.17673v2 Announce Type: replace Abstract: Despite their empirical success, how diffusion models generalize remains poorly understood from a mechanistic perspective. In this work, we provide a controlled mechanistic account of algorithmic learning in diffusion models. By…
