Better Cardinality Estimators for HyperLogLog, PCSA, and Beyond
Summary: Introduce tau-Generalized-Remaining-Area (tau-GRA) estimators and a simpler unified analysis that casts prior estimators as integer‑tau cases. Fractional tau yields improved HyperLogLog/PCSA estimators near Cramér‑Rao variance and better Curtain‑sketch tradeoffs. (summarized by gpt-5-mini on Feb 09 2026)
