Jincheng Gong, Huanhuan Li, Hang Jiao, Zaili Yang

Project |

• Introduced a novel ship trajectory prediction benchmark for Maritime Autonomous Surface Ships (MASS).
• Developed an advanced trajectory prediction algorithm that integrates spatio-temporal and probabilistic modelling.
• Pioneered an uncertainty-aware feature modelling approach to improve prediction reliability and interpretability.
• Validated the model’s performance across three benchmark datasets using three key evaluation metrics.

Project |

• Propose LLM4STP, a novel multi-feature fusion method integrating LLMs and maritime knowledge for improved ship trajectory prediction.
• Introduce an adaptive graph-masked Transformer for dynamic ship interaction modelling, capturing complex spatial relationships.
• Combine local convolution and global LLM inference for effective multi-scale temporal modelling.
• Establish a system for trajectory uncertainty quantification using 2D Gaussian heatmaps and Geohash-based encoding.
