Privacy-Preserving Distributed Optimisation using Stochastic PDMM

no code implementations13 Dec 2023 Sebastian O. Jordan, Qiongxiu Li, Richard Heusdens

The main idea is to exploit a certain structure in the update equations for noise insertion such that the private data is protected without compromising the algorithm's accuracy.

On the Privacy Effect of Data Enhancement via the Lens of Memorization

1 code implementation17 Aug 2022 Xiao Li, Qiongxiu Li, Zhanhao Hu, Xiaolin Hu

We demonstrate that the generalization gap and privacy leakage are less correlated than those of the previous results.

Privacy-Preserving Distributed Optimization via Subspace Perturbation: A General Framework

1 code implementation29 Apr 2020 Qiongxiu Li, Richard Heusdens, Mads Græsbøll Christensen

We therefore propose to insert noise in the non-convergent subspace through the dual variable such that the private data are protected, and the accuracy of the desired solution is completely unaffected.
