稳健性与局部差分隐私

研究问题
研究在 Huber 污染与局部差分隐私同时存在时,稳健性和隐私各带来何种统计代价,以及两类方法能否相互兼容。
方法与思路
作者先给出一般极小极大下界,再考察两点检验、可能发散的均值、非参数密度和单变量中位数四类问题。
材料陈述的贡献
摘要称下界分离了污染与隐私的代价,并为四类问题构造兼具约束下的最优程序,部分回答稳健化与隐私化的联系。
阅读关注点
应核对污染模型、隐私机制和损失函数,以及下界中的代价分解、各程序最优性的范围和兼容性结论的限制。
阅读边界
仅依据版本未注明的 OpenAlex 索引摘要;未给最优速率和条件,作者的优先性陈述未经核验,不能概括为全面兼容。

原文摘要

It is of soaring demand to develop statistical analysis tools that are robust against contamination as well as preserving individual data owners’ privacy. In spite of the fact that both topics host a rich body of literature, to the best of our knowledge, we are the first to systematically study the connections between the optimality under Huber’s contamination model and the local differential privacy (LDP) constraints. In this paper, we start with a general minimax lower bound result, which disentangles the costs of being robust against Huber contamination and preserving LDP. We further study four concrete examples: a two-point testing problem, a potentially diverging mean estimation problem, a nonparametric density estimation problem and a univariate median estimation problem. For each problem, we demonstrate procedures that are optimal in the presence of both contamination and LDP constraints, comment on the connections with the state-of-the-art methods that are only studied under either contamination or privacy constraints, and unveil the connections between robustness and LDP via partially answering whether LDP procedures are robust and whether robust procedures can be efficiently privatised. Overall, our work showcases a promising prospect of joint study for robustness and local differential privacy.
