Real-Time Distance-Based Outlier Detection in Data Streams
Summary: CPOD introduces a core-point with multi-distance indexing for real-time distance-based outlier detection in streaming data on edge devices. Memory-efficient; up to 73x faster than MCOD/NETS/M_MCOD across six real-world and one synthetic dataset by shrinking neighbor search. (summarized by gpt-5-nano on Feb 09 2026)
