DeepTEA: Effective and Efficient Online Time-dependent Trajectory Outlier Detection
Summary: DeepTEA models time- and location-varying traffic with deep probabilistic learning for trajectory outlier detection. A fast approximate variant enables online, real-time analysis at million-trajectory scale while improving accuracy over seven baselines by 17.52%. (summarized by gpt-5.6-luna on Jul 24 2026)
