A meshfree exterior calculus for generalizable and data-efficient learning of physics from point clouds

Researchers introduce MEEC (meshfree exterior calculus), a novel framework for learning physics directly from point clouds without requiring mesh generation. MEEC-Net, built on this approach, demonstrates 1-2 orders of magnitude better generalization across different geometries, resolutions, and physical parameters compared to existing neural operator methods, achieving this with minimal training data.

SPADE: Structure-Prior Adaptive Decision Estimation

SPADE introduces a machine learning framework that adaptively decides whether to enforce physical-structure priors (conservation laws, Hamiltonian forms) based on data evidence, using statistical tests and shrinkage estimation. The method automatically calibrates prior enforcement strength and selects among competing structures, achieving oracle-level performance while reducing computational overhead compared to cross-validation approaches.

Vision Language Models Cannot Reason About Physical Transformation

Researchers demonstrate that Vision Language Models systematically fail to understand physical transformations, revealing fundamental gaps in how these AI systems reason about dynamic environments. Through ConservationBench testing 112 VLMs on conservation principles, the study shows models perform near chance levels regardless of prompting strategies or temporal resolution, indicating they lack genuine comprehension of invariant physical properties rather than simply lacking training data.
