Understanding Practical Membership Privacy of Deep Learning

no code implementations7 Feb 2024 Marlon Tobaben, Gauri Pradhan, Yuan He, Joonas Jälkö, Antti Honkela

We apply a state-of-the-art membership inference attack (MIA) to systematically test the practical privacy vulnerability of fine-tuning large image classification models. We focus on understanding the properties of data sets and samples that make them vulnerable to membership inference.

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.

PyVBMC: Efficient Bayesian inference in Python

1 code implementation16 Mar 2023 Bobby Huggins, Chengkun Li, Marlon Tobaben, Mikko J. Aarnos, Luigi Acerbi

PyVBMC is a Python implementation of the Variational Bayesian Monte Carlo (VBMC) algorithm for posterior and model inference for black-box computational models (Acerbi, 2018, 2020).

On the Efficacy of Differentially Private Few-shot Image Classification

1 code implementation2 Feb 2023 Marlon Tobaben, Aliaksandra Shysheya, John Bronskill, Andrew Paverd, Shruti Tople, Santiago Zanella-Beguelin, Richard E Turner, Antti Honkela

There has been significant recent progress in training differentially private (DP) models which achieve accuracy that approaches the best non-private models.

Individual Privacy Accounting with Gaussian Differential Privacy

1 code implementation30 Sep 2022 Antti Koskela, Marlon Tobaben, Antti Honkela

In order to account for the individual privacy losses in a principled manner, we need a privacy accountant for adaptive compositions of randomised mechanisms, where the loss incurred at a given data access is allowed to be smaller than the worst-case loss.
