Multi-Model Synthetic Training for Mission-Critical Small Language Models

Researchers demonstrate a cost-effective approach to training specialized small language models by using LLMs as one-time teachers to generate synthetic training data. By converting 3.2 billion maritime vessel tracking records into 21,543 QA pairs, they fine-tuned Qwen2.5-7B to achieve 75% accuracy on maritime tasks at a fraction of the cost of deploying larger models, establishing a reproducible framework for domain-specific AI applications.

Sim2Sea: Sim-to-Real Policy Transfer for Maritime Vessel Navigation in Congested Waters

Researchers have developed Sim2Sea, a comprehensive framework that successfully bridges the simulation-to-reality gap for autonomous maritime vessel navigation in congested waters. The system uses GPU-accelerated parallel simulation, dual-stream spatiotemporal policy, and targeted domain randomization to achieve zero-shot transfer from simulation to real-world deployment on a 17-ton unmanned vessel.

AIS-Based Vessel Trajectory Prediction Using Memory-Augmented Neural Networks

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.

SKETCH: Semantic Key-Point Conditioning for Long-Horizon Vessel Trajectory Prediction

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.

Joint Estimation of Sea State and Vessel Parameters Using a Mass-Spring-Damper Equivalence Model

Researchers developed a new method for real-time sea state estimation that jointly estimates both sea conditions and vessel parameters without requiring prior knowledge of wave-vessel transfer functions. The approach uses a mass-spring-damper model with advanced filtering techniques to achieve performance matching traditional methods that assume complete transfer function knowledge.
