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.

Detecting Deepfakes via Hamiltonian Dynamics

Researchers propose Hamiltonian Action Anomaly Detection (HAAD), a physics-inspired deepfake detection method that analyzes dynamical stability rather than static patterns. The approach models images as energy states, hypothesizing that authentic images settle in stable, low-energy configurations while deepfakes occupy unstable, high-energy states, demonstrating superior cross-dataset performance.

Physically Native World Models: A Hamiltonian Perspective on Generative World Modeling

Researchers propose Hamiltonian World Models, a physics-grounded approach to generative world modeling that encodes observations into structured latent phase spaces and evolves them through Hamiltonian-inspired dynamics. The framework aims to address limitations in current world models by prioritizing physical accuracy and action-controllability alongside visual realism, with applications to robotics, autonomous driving, and reinforcement learning.
