-leakage by Rényi Divergence and Sibson Mutual Information
Ni Ding, Mohammad Amin Zarrabian, Parastoo Sadeghi
For , this paper proposes a -mean information gain measure. Rényi divergence is shown to be the maximum -mean information g…
A Cross Entropy Interpretation of R{é}nyi Entropy for -leakage
Ni Ding, Mohammad Amin Zarrabian, Parastoo Sadeghi
This paper proposes an -leakage measure for by a cross entropy interpretation of R{é}nyi entropy. While Rényi entropy was originally defined as an -mean for…
Approximation of Pufferfish Privacy for Gaussian Priors
Ni Ding
This paper studies how to approximate pufferfish privacy when the adversary's prior belief of the published data is Gaussian distributed. Using Monge's optimal transport plan, we s…
On the Lift, Related Privacy Measures, and Applications to Privacy-Utility Tradeoffs
Mohammad Amin Zarrabian, Ni Ding, Parastoo Sadeghi
This paper investigates lift, the likelihood ratio between the posterior and prior belief about sensitive features in a dataset. Maximum and minimum lifts over sensitive features q…
A Faster Algorithm for Asymptotic Communication for Omniscience
Ni Ding, Chung Chan, Qiaoqiao Zhou +2
We propose a modified decomposition algorithm (MDA) to solve the asymptotic communication for omniscience (CO) problem where the communication rates could be real or fractional. By…
