Benchmarking the Utility of w-event Differential Privacy Mechanisms - When Baselines Become Mighty Competitors

Summary: Introduces a comparability-focused benchmark for evaluating w-event differential privacy mechanisms on streams, addressing inconsistencies in prior studies. Large-scale results reveal “baseline supremacy”: standard baselines often match or outperform specialized mechanisms. (summarized by gpt-5.6-luna on Jul 24 2026)
