Free Gap Information from the Differentially Private Sparse Vector and Noisy Max Mechanisms
Summary: Free-gap from Noisy Max: release the noisy gap to the runner-up at no extra privacy cost, boosting downstream counting accuracy by up to 50%. Sparse Vector: adaptively budget privacy, spending less on queries well above threshold to process more queries, via a careful privacy analysis. (summarized by gpt-5-nano on Feb 09 2026)
