Optimizing error of high-dimensional statistical queries under differential privacy
Summary: HDMM optimizes differentially private mechanisms for predicate-counting workloads by compactly representing high-dimensional query matrices and searching the mechanism space efficiently. It achieves lower error than prior methods across low- and high-dimensional datasets without their computational bottlenecks. (summarized by gpt-5.6-luna on Jul 24 2026)
