About the Cost of Central Privacy in Density Estimation

no code implementations26 Jun 2023 Clément Lalanne, Aurélien Garivier, Rémi Gribonval

We recover the result of Barber \& Duchi (2014) stating that histogram estimators are optimal against Lipschitz distributions for the L2 risk, and under regular differential privacy, and we extend it to other norms and notions of privacy.

Sparsity in neural networks can improve their privacy

no code implementations20 Apr 2023 Antoine Gonon, Léon Zheng, Clément Lalanne, Quoc-Tung Le, Guillaume Lauga, Can Pouliquen

This article measures how sparsity can make neural networks more robust to membership inference attacks.

Sparsity in neural networks can increase their privacy

no code implementations11 Apr 2023 Antoine Gonon, Léon Zheng, Clément Lalanne, Quoc-Tung Le, Guillaume Lauga, Can Pouliquen

This article measures how sparsity can make neural networks more robust to membership inference attacks.

Private Statistical Estimation of Many Quantiles

no code implementations14 Feb 2023 Clément Lalanne, Aurélien Garivier, Rémi Gribonval

The first one consists in privately estimating the empirical quantiles of the samples and using this result as an estimator of the quantiles of the distribution.

On the Statistical Complexity of Estimation and Testing under Privacy Constraints

no code implementations5 Oct 2022 Clément Lalanne, Aurélien Garivier, Rémi Gribonval

In certain scenarios, we show that maintaining privacy results in a noticeable reduction in performance only when the level of privacy protection is very high.

Extraction of Nystagmus Patterns from Eye-Tracker Data with Convolutional Sparse Coding

1 code implementation25 Nov 2020 Clément Lalanne, Maxence Rateaux, Laurent Oudre, Matthieu Robert, Thomas Moreau

The analysis of the Nystagmus waveforms from eye-tracking records is crucial for the clinicial interpretation of this pathological movement.
