Mean Estimation Under Heterogeneous Privacy Demands

no code implementations19 Oct 2023 Syomantak Chaudhuri, Konstantin Miagkov, Thomas A. Courtade

As a consequence, users with less but differing privacy requirements are all given more privacy than they require, in equal amounts.

Mean Estimation Under Heterogeneous Privacy: Some Privacy Can Be Free

no code implementations27 Apr 2023 Syomantak Chaudhuri, Thomas A. Courtade

Differential Privacy (DP) is a well-established framework to quantify privacy loss incurred by any algorithm.

Online Target Q-learning with Reverse Experience Replay: Efficiently finding the Optimal Policy for Linear MDPs

no code implementations ICLR 2022 Naman Agarwal, Syomantak Chaudhuri, Prateek Jain, Dheeraj Nagaraj, Praneeth Netrapalli

The starting point of our work is the observation that in practice, Q-learning is used with two important modifications: (i) training with two networks, called online network and target network simultaneously (online target learning, or OTL) , and (ii) experience replay (ER) (Mnih et al., 2015).
