From Uniform to Learned Graph Priors: Diffusion for Structure Discovery
Researchers have developed a new method called Diff-prior to improve neural relational inference (NRI) for discovering interaction graphs from data. Current NRI methods often use overly simplistic priors that lead to unreliable structural discovery. Diff-prior reframes the integration of priors as a learnable denoising process, calibrating uncertain edge posteriors into a more reliable structure. This approach has shown improved performance and more decisive edge posteriors across various NRI architectures on standard benchmarks. AI
