Coordinated Weighted Sampling for Estimating Aggregates Over Multiple Weight Assignments
Summary: Coordinated weighted sampling for vector-weighted keys enables accurate aggregates across multiple weight assignments (time snapshots, multi-location requests). A unified framework with estimators orders of magnitude tighter than single-weight designs; empirically validated on IP networks and stock quotes data. (summarized by gpt-5-nano on Feb 09 2026)
