From Uniform to Learned Graph Priors: Diffusion for Structure Discovery

arXiv:2606.11831v1 Announce Type: new Abstract: Neural relational inference (NRI) methods discover interaction graphs from trajectories through variational reasoning on discrete potential edges. However, these methods typically rely on oversimplified, factorized graph priors. Such priors, typically nearing uniform distributions, treat edges as independent entities. This systemic misalignment does not match the real-world systems and yields diffuse and indecisive edge posteriors limiting the reliability of structural discovery. To address this, we propose \textit{Diff-prior}, a diffusion-parame

Why this matters
Why now

The paper introduces a novel approach to address a known limitation in current neural relational inference methods by leveraging diffusion models for more realistic graph priors.

Why it’s important

Improved structural discovery in AI agents through more accurate interaction modeling enhances their reliability and performance in complex, real-world systems.

What changes

AI systems will be able to infer relationships between entities more precisely, moving beyond oversimplified assumptions and leading to more robust decision-making and understanding.
