Kamel: A Scalable BERT-based System for Trajectory Imputation

Summary: Kamel recasts trajectory imputation as masked-word prediction, adapting BERT with spatial awareness and multi-point inference. Its scalable design handles city-scale trajectories, large gaps, and tight accuracy thresholds, outperforming prior methods on real data. (summarized by gpt-5.6-luna on Jul 24 2026)
