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.
