When approximate design for fast homomorphic computation provides differential privacy guarantees

no code implementations6 Apr 2023 Arnaud Grivet Sébert, Martin Zuber, Oana Stan, Renaud Sirdey, Cédric Gouy-Pailler

While machine learning has become pervasive in as diversified fields as industry, healthcare, social networks, privacy concerns regarding the training data have gained a critical importance.

SPEED: Secure, PrivatE, and Efficient Deep learning

no code implementations16 Jun 2020 Arnaud Grivet Sébert, Rafael Pinot, Martin Zuber, Cédric Gouy-Pailler, Renaud Sirdey

Based on collaborative learning, differential privacy and homomorphic encryption, the proposed approach advances state-of-the-art of private deep learning against a wider range of threats, in particular the honest-but-curious server assumption.

A unified view on differential privacy and robustness to adversarial examples

no code implementations19 Jun 2019 Rafael Pinot, Florian Yger, Cédric Gouy-Pailler, Jamal Atif

This short note highlights some links between two lines of research within the emerging topic of trustworthy machine learning: differential privacy and robustness to adversarial examples.

On the Needs for Rotations in Hypercubic Quantization Hashing

no code implementations12 Feb 2018 Anne Morvan, Antoine Souloumiac, Krzysztof Choromanski, Cédric Gouy-Pailler, Jamal Atif

The aim of this paper is to endow the well-known family of hypercubic quantization hashing methods with theoretical guarantees.

Streaming Binary Sketching based on Subspace Tracking and Diagonal Uniformization

no code implementations22 May 2017 Anne Morvan, Antoine Souloumiac, Cédric Gouy-Pailler, Jamal Atif

We demonstrate the quality of our binary sketches through experiments on real data for the nearest neighbors search task in the online setting.

Graph sketching-based Space-efficient Data Clustering

1 code implementation7 Mar 2017 Anne Morvan, Krzysztof Choromanski, Cédric Gouy-Pailler, Jamal Atif

In this paper, we address the problem of recovering arbitrary-shaped data clusters from datasets while facing \emph{high space constraints}, as this is for instance the case in many real-world applications when analysis algorithms are directly deployed on resources-limited mobile devices collecting the data.

Multi-dimensional signal approximation with sparse structured priors using split Bregman iterations

no code implementations29 Sep 2016 Yoann Isaac, Quentin Barthélemy, Cédric Gouy-Pailler, Michèle Sebag, Jamal Atif

This paper addresses the structurally-constrained sparse decomposition of multi-dimensional signals onto overcomplete families of vectors, called dictionaries.

Multi-dimensional sparse structured signal approximation using split Bregman iterations

no code implementations21 Mar 2013 Yoann Isaac, Quentin Barthélemy, Jamal Atif, Cédric Gouy-Pailler, Michèle Sebag

An extensive empirical evaluation shows how the proposed approach compares to the state of the art depending on the signal features.
