RGS-Sketch: An Accurate, Invertible, and Mergeable Sketch for Online Super Spreader Detection in High-speed Data Streams
Summary: Introduces RGS-Sketch, a mergeable, invertible, online-capable sketch that uses register-group sharing to adaptively allocate memory for skewed high-speed streams, improving memory efficiency and enabling real-time state access. Adds a limited-register update rule to block small flows and reduce noise, yielding large F1 improvements over prior methods across single- and multi-point measurements.
