内容简介：（须有英文介绍）
Differential privacy is a state-of-the-art concept in data privacy reseach and applications. In this talk, I will present some recent methodological and application work my group has developed, including methods for differentially private data synthesis and its applications in tabular data, graphs, and location data; differentially private empirical risk minimization with dual-purpose regularizer; and differentially private machine learning through iterative optimization procedures. Statistical challenges and opportunies will also be discussed.
差分隐私是数据隐私研究和应用程序中最先进的概念。本报告中将介绍该团队最近开发的一些方法论和应用工作，包括差分私有数据合成方法及其在表格数据，图形和位置数据中的应用;使用双重用途正则化器的差异化私人经验风险最小化;以及通过迭代优化过程进行差分私有机器学习。还将讨论统计方面的挑战和机会。
