What’s Hot and What’s Not: Tracking Most Frequent Items Dynamically
Summary: Small-space dynamic algorithm that reports all hot (frequent) items under inserts and deletions with user-specified success probability and without rescanning the DB. Uses group-testing to achieve simple implementation and provable space/time/accuracy guarantees, unlike prior work. (summarized by gpt-5-mini on Feb 09 2026)
