Private Mean Estimation Impossible Without Covariance, Study Finds
A new research paper published on arXiv explores the limitations of differentially private Gaussian mean estimation when the covariance matrix is unknown. The study establishes lower bounds demonstrating that private es…

New minimax-quantile theory enhances privacy in statistical decision making
Researchers have developed a new minimax-quantile theory for interactive statistical decision making (ISDM) that addresses rare but significant failures, which traditional expectation-based criteria like minimax risk an…

New metric 'empirical sensitivity' introduced for statistical estimators
Researchers have introduced a new metric called "empirical sensitivity" to measure the robustness of statistical estimators. This metric quantifies how much an estimator's output changes when a small fraction of the inp…
