Asking the World: Generalist Physical Reasoning through Agentic World Modeling and Probing

This work introduces Asking the World (ATW), a generalist agent that constructs and interrogates task-relevant executable worlds through two adaptive stages: World Modeling calibrates a world from video, while World Probing queries, simulates, and intervenes on it to obtain question-relevant evidence.

Beyond Arbitrary Geometry: Topology Generalization In neural PDE Operators

Topology is established as a distinct generalization axis beyond arbitrary-geometry compatibility and influence extends across the Hodge spectrum rather than remaining confined to the harmonic kernel, and global, low-frequency structural priors may help organize predictions in the faster-decaying complementary componen...
