New AI framework discovers Lie symmetries in stochastic systems

By PulseAugur Editorial · [1 sources] ·

Researchers have developed LieStoNet, a novel framework designed to identify Lie-point symmetries in stochastic differential equations (SDEs) directly from spatiotemporal data. This template-free approach learns neural surrogates for drift and diffusion, then enforces SDE determining equations and Lie algebra axioms to discover symmetries. The system can also discover symmetries for the associated Fokker-Planck equation, offering interpretable insights into noisy dynamical systems. AI

IMPACT This framework could enable more robust and interpretable modeling of complex physical systems by automatically uncovering underlying symmetries.

    LieStoNet: Learning Lie Symmetries from Spatiotemporal Data for Stochastic Dynamical Systems

    arXiv:2608.01582v1 Announce Type: cross Abstract: Symmetry is central to modern machine learning and physics: invariances and equivariances improve sample efficiency, robustness, and out-of-distribution generalization, while symmetry principles guide scientific modeling. Yet for …
