Three Variants of Differential Privacy: Lossless Conversion and Applications

no code implementations14 Aug 2020 Shahab Asoodeh, Jiachun Liao, Flavio P. Calmon, Oliver Kosut, Lalitha Sankar

In the first part, we develop a machinery for optimally relating approximate DP to RDP based on the joint range of two $f$-divergences that underlie the approximate DP and RDP.

A Better Bound Gives a Hundred Rounds: Enhanced Privacy Guarantees via $f$-Divergences

no code implementations16 Jan 2020 Shahab Asoodeh, Jiachun Liao, Flavio P. Calmon, Oliver Kosut, Lalitha Sankar

We derive the optimal differential privacy (DP) parameters of a mechanism that satisfies a given level of R\'enyi differential privacy (RDP).

Theoretical Guarantees for Model Auditing with Finite Adversaries

no code implementations8 Nov 2019 Mario Diaz, Peter Kairouz, Jiachun Liao, Lalitha Sankar

Privacy concerns have led to the development of privacy-preserving approaches for learning models from sensitive data.

Generating Fair Universal Representations using Adversarial Models

no code implementations27 Sep 2019 Peter Kairouz, Jiachun Liao, Chong Huang, Maunil Vyas, Monica Welfert, Lalitha Sankar

We present a data-driven framework for learning fair universal representations (FUR) that guarantee statistical fairness for any learning task that may not be known a priori.
