S-GBDT: Frugal Differentially Private Gradient Boosting Decision Trees

no code implementations21 Sep 2023 Moritz Kirschte, Thorsten Peinemann, Joshua Stock, Carlos Cotrini, Esfandiar Mohammadi

For the Abalone dataset for $\varepsilon=0. 54$ we achieve $R^2$-score of $0. 47$ which is very close to the $R^2$-score of $0. 54$ for the nonprivate version of GBDT.

The Applicability of Federated Learning to Official Statistics

no code implementations28 Jul 2023 Joshua Stock, Oliver Hauke, Julius Weißmann, Hannes Federrath

This work investigates the potential of Federated Learning (FL) for official statistics and shows how well the performance of FL models can keep up with centralized learning methods. F L is particularly interesting for official statistics because its utilization can safeguard the privacy of data holders, thus facilitating access to a broader range of data.

Lessons Learned: Defending Against Property Inference Attacks

no code implementations18 May 2022 Joshua Stock, Jens Wettlaufer, Daniel Demmler, Hannes Federrath

Extensive experiments with property unlearning show that while it is very effective when defending target models against specific adversaries, property unlearning is not able to generalize, i. e., protect against a whole class of PIAs.
