Time-Decaying Aggregates in Out-of-order Streams

Summary: First deterministic algorithms for time‑decayed aggregates on out‑of‑order streams (sliding window, polynomial/exponential), supporting range queries, quantiles, and heavy hitters where EH/Waves fail. Analytically and experimentally quantifies overhead/tradeoffs versus well‑ordered arrivals. (summarized by gpt-5-mini on Feb 09 2026)
