Researchers develop a large language model framework for predicting vessel trajectories and destinations up to 30 days in advance using reinforcement learning with verifiable rewards. The approach outperforms traditional deep learning methods by maintaining route feasibility and destination accuracy over extended maritime forecasting horizons.
Researchers demonstrate that memory-augmented neural networks significantly improve vessel trajectory prediction using AIS maritime data from the Gulf of Mexico and New York Bight. The approach selectively retrieves relevant historical information to outperform conventional deep learning models, with applications for collision avoidance and maritime route optimization.
Researchers propose SKETCH, a semantic key-point-conditioned framework that improves long-horizon vessel trajectory prediction by decomposing the problem into high-level navigational intent and local motion modeling. The method outperforms existing approaches on real-world AIS data, particularly for extended time horizons and directional accuracy.
Researchers introduce CmIVTP, a cross-modal AI framework that combines AIS and CCTV data to improve maritime vessel trajectory prediction. The system uses transformer-based architecture with attention mechanisms to model vessel-environment interactions, addressing limitations of single-source data in maritime navigation systems.
Researchers introduce VISTA, a framework for vessel trajectory imputation that uses knowledge-driven LLM reasoning to repair incomplete maritime tracking data. The system provides 'repair provenance' - documented reasoning behind data repairs - achieving 5-91% accuracy improvements over existing methods while reducing inference time by 51-93%.
