Kamel: A Scalable BERT-based System for Trajectory Imputation
Summary: Kamel maps trajectory imputation to masked-token prediction, using BERT extended with spatial-awareness and trajectory-tailored preprocessing for multi-point filling. These system-level extensions enable scalable, city-scale imputation with higher accuracy on large spatio-temporal gaps than prior approaches. (summarized by gpt-5-mini on Feb 09 2026)
