Addressing Membership Inference Attack in Federated Learning with Model Compression

1 code implementation29 Nov 2023 Gergely Dániel Németh, Miguel Ángel Lozano, Novi Quadrianto, Nuria Oliver

In this paper, we show that the effectiveness of these attacks on the clients negatively correlates with the size of the client datasets and model complexity.

Structural Group Unfairness: Measurement and Mitigation by means of the Effective Resistance

no code implementations5 May 2023 Adrian Arnaiz-Rodriguez, Georgina Curto, Nuria Oliver

We denote the social capital disparity among different groups in a network as structural group unfairness, and propose to mitigate it by means of a budgeted edge augmentation heuristic that systematically increases the social capital of the most disadvantaged group.
