Bus-Conditioned Zero-Shot Trajectory Generation via Task Arithmetic
Shuai Liu, Ning Cao, Yile Chen +2
Mobility trajectory data provide essential support for smart city applications. However, such data are often difficult to obtain. Meanwhile, most existing trajectory generation met…
STRATA-TS: Selective Knowledge Transfer for Urban Time Series Forecasting with Retrieval-Guided Reasoning
Yue Jiang, Chenxi Liu, Yile Chen +4
Urban forecasting models often face a severe data imbalance problem: only a few cities have dense, long-span records, while many others expose short or incomplete histories. Direct…
NextLocLLM: Location Semantics Modeling and Coordinate-Based Next Location Prediction with LLMs
Shuai Liu, Ning Cao, Yile Chen +3
Next location prediction is a critical task in human mobility analysis.Existing methods typically formulate it as a classification task based on discrete location IDs, which hinder…
