Safety-screened physics-informed hierarchical diffusion for near-real-time AIS-based vessel trajectory prediction

Automatic Identification System (AIS)-based vessel trajectory prediction is an important component of maritime traffic safety and decision support in busy waterways, port approaches, and restricted waters. In such areas, prediction accuracy alone is insufficient: predicted motion should remain physically plausible,...

RCShift: Certifying When Partial Linkage Suffices for Finite-Sample Decisions

This work introduces RCShift, which certifies two routes to sufficiency under a declared observation contract, and exact mode characterizes minimum-cost family-exact storage through LR-visible cycle directions through LR-visible cycle directions.
