SPAS: Continuous Release of Data Streams under w-Event Differential Privacy
Summary: SPAS enables continuous data release under w-event DP with data-dependent sliding-window publishing, reducing error. It uses a weighted sparse-vector technique to adapt sampling and budget, enabling release and range queries on diverse streams. (summarized by gpt-5-nano on Feb 09 2026)
