Towards Biologically Plausible and Private Gene Expression Data Generation

1 code implementation7 Feb 2024 Dingfan Chen, Marie Oestreich, Tejumade Afonja, Raouf Kerkouche, Matthias Becker, Mario Fritz

In this paper, we initiate a systematic analysis of how DP generative models perform in their natural application scenarios, specifically focusing on real-world gene expression data.

Privacy-Aware Document Visual Question Answering

no code implementations15 Dec 2023 Rubèn Tito, Khanh Nguyen, Marlon Tobaben, Raouf Kerkouche, Mohamed Ali Souibgui, Kangsoo Jung, Lei Kang, Ernest Valveny, Antti Honkela, Mario Fritz, Dimosthenis Karatzas

We employ a federated learning scheme, that reflects the real-life distribution of documents in different businesses, and we explore the use case where the ID of the invoice issuer is the sensitive information to be protected.

A Unified View of Differentially Private Deep Generative Modeling

no code implementations27 Sep 2023 Dingfan Chen, Raouf Kerkouche, Mario Fritz

The availability of rich and vast data sources has greatly advanced machine learning applications in various domains.

Client-specific Property Inference against Secure Aggregation in Federated Learning

1 code implementation7 Mar 2023 Raouf Kerkouche, Gergely Ács, Mario Fritz

We formulate an optimization problem across different rounds in order to infer a tested property of every client from the output of the linear models, for example, whether they have a specific sample in their training data (membership inference) or whether they misbehave and attempt to degrade the performance of the common model by poisoning attacks.

Private Set Generation with Discriminative Information

2 code implementations7 Nov 2022 Dingfan Chen, Raouf Kerkouche, Mario Fritz

Differentially private data generation techniques have become a promising solution to the data privacy challenge -- it enables sharing of data while complying with rigorous privacy guarantees, which is essential for scientific progress in sensitive domains.

Practical Challenges in Differentially-Private Federated Survival Analysis of Medical Data

no code implementations8 Feb 2022 Shadi Rahimian, Raouf Kerkouche, Ina Kurth, Mario Fritz

Survival analysis or time-to-event analysis aims to model and predict the time it takes for an event of interest to happen in a population or an individual.

Constrained Differentially Private Federated Learning for Low-bandwidth Devices

no code implementations27 Feb 2021 Raouf Kerkouche, Gergely Ács, Claude Castelluccia, Pierre Genevès

This bandwidth and corresponding processing costs could be prohibitive if the participating entities are, for example, mobile devices.

Compression Boosts Differentially Private Federated Learning

no code implementations10 Nov 2020 Raouf Kerkouche, Gergely Ács, Claude Castelluccia, Pierre Genevès

In this paper, compressive sensing is used to reduce the model size and hence increase model quality without sacrificing privacy.

Federated Learning in Adversarial Settings

no code implementations15 Oct 2020 Raouf Kerkouche, Gergely Ács, Claude Castelluccia

This paper presents a new federated learning scheme that provides different trade-offs between robustness, privacy, bandwidth efficiency, and model accuracy.
