From GPS Points to Travel Patterns: Flexible and Semantic Trajectory Generation with LLMs 事件

From GPS Points to Travel Patterns: Flexible and Semantic Trajectory Generation with LLMs arXiv:2605.30014v1 Announce Type: new Abstract: Urban trajectories play a crucial role in modeling urban dynamics and supporting various smart city applications. However, privacy concerns restrict access to large-scale and high-quality trajectory datasets. Trajectory generation provides a promising alternative by synthesizing realistic data to mitigate privacy risks. However, existing methods fail to expli
