Errata for "SpaceSaving+-: An Optimal Algorithm for Frequency Estimation and Frequent Items in the Bounded-Deletion Model"
Summary: Errata exposes an implicit assumption in VLDB'22 SpaceSaving+-: it assumed deletions occur after insertions, and interleaving can cause severe underestimation in the bounded-deletion model. Presents minor algorithmic modifications to handle interleaving and points to a full analysis of the corrected algorithms. (summarized by gpt-5-mini on Feb 09 2026)
