Researchers have developed a novel probabilistic symbolic regression framework designed to enhance AI-driven scientific discovery. This new method represents mathematical expressions as ensembles of symbolic trees, utilizing a regularizing prior to manage expression complexity and an Occam's window-based posterior to capture uncertainty across multiple plausible models. The framework has demonstrated superior predictive accuracy, optimal symbolic complexity, and stable structural recovery when learning benchmark scientific equations, and has also been applied to identify interpretable descriptors in materials discovery.
