Fairness and Privacy Guarantees in Federated Contextual Bandits

no code implementations5 Feb 2024 Sambhav Solanki, Shweta Jain, Sujit Gujar

We design a novel communication protocol that allows for (i) Sub-linear theoretical bounds on fairness regret for Fed-FairX-LinUCB and comparable bounds for the private counterpart, Priv-FairX-LinUCB (relative to single-agent learning), (ii) Effective use of privacy budget in Priv-FairX-LinUCB.

Efficient Algorithms For Fair Clustering with a New Fairness Notion

1 code implementation2 Sep 2021 Shivam Gupta, Ganesh Ghalme, Narayanan C. Krishnan, Shweta Jain

We revisit the problem of fair clustering, first introduced by Chierichetti et al., that requires each protected attribute to have approximately equal representation in every cluster; i. e., a balance property.

Designing Truthful Contextual Multi-Armed Bandits based Sponsored Search Auctions

no code implementations26 Feb 2020 Kumar Abhishek, Shweta Jain, Sujit Gujar

It is in the best interest of the center to select an ad that has a high expected value (i. e., probability of getting a click $\times$ value it derives from a click of the ad).

Ballooning Multi-Armed Bandits

no code implementations24 Jan 2020 Ganesh Ghalme, Swapnil Dhamal, Shweta Jain, Sujit Gujar, Y. Narahari

In this paper, we introduce Ballooning Multi-Armed Bandits (BL-MAB), a novel extension of the classical stochastic MAB model.
