VISTA: Knowledge-Driven Vessel Trajectory Imputation with Repair Provenance
arXiv – CS AI|Hengyu Liu, Tianyi Li, Haoyu Wang, Kristian Torp, Tiancheng Zhang, Yushuai Li, Christian S. Jensen||17 views
🤖AI Summary
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%.
Key Takeaways
- →VISTA framework introduces 'repair provenance' to document reasoning behind trajectory data repairs, enhancing trust in safety-critical maritime applications.
- →The system uses Structured Data-derived Knowledge (SDK) to ground LLM reasoning in verifiable data from large-scale AIS datasets.
- →VISTA achieves 5-91% accuracy improvements over baseline methods while reducing inference time by 51-93%.
- →The framework includes workflow management with parallel scheduling and fault tolerance for consistent processing.
- →Research addresses critical need for interpretable AI in maritime anomaly detection and route planning applications.
