Sliced-Wasserstein Estimation with Spherical Harmonics as Control Variates

no code implementations2 Feb 2024 Rémi Leluc, Aymeric Dieuleveut, François Portier, Johan Segers, Aigerim Zhuman

Spherical harmonics are polynomials on the sphere that form an orthonormal basis of the set of square-integrable functions on the sphere.

Compression with Exact Error Distribution for Federated Learning

no code implementations31 Oct 2023 Mahmoud Hegazy, Rémi Leluc, Cheuk Ting Li, Aymeric Dieuleveut

Compression schemes have been extensively used in Federated Learning (FL) to reduce the communication cost of distributed learning.

MARLIM: Multi-Agent Reinforcement Learning for Inventory Management

no code implementations3 Aug 2023 Rémi Leluc, Elie Kadoche, Antoine Bertoncello, Sébastien Gourvénec

Maintaining a balance between the supply and demand of products by optimizing replenishment decisions is one of the most important challenges in the supply chain industry.

Membership Inference Attacks via Adversarial Examples

no code implementations27 Jul 2022 Hamid Jalalzai, Elie Kadoche, Rémi Leluc, Vincent Plassier

In this paper, we develop a mean to measure the leakage of training data leveraging a quantity appearing as a proxy of the total variation of a trained model near its training samples.

A Quadrature Rule combining Control Variates and Adaptive Importance Sampling

no code implementations24 May 2022 Rémi Leluc, François Portier, Johan Segers, Aigerim Zhuman

Within the standard adaptive importance sampling framework, a simple weighted least squares approach is proposed to improve the procedure with control variates.

SGD with Coordinate Sampling: Theory and Practice

1 code implementation25 May 2021 Rémi Leluc, François Portier

While classical forms of stochastic gradient descent algorithm treat the different coordinates in the same way, a framework allowing for adaptive (non uniform) coordinate sampling is developed to leverage structure in data.

Feature Clustering for Support Identification in Extreme Regions

no code implementations13 Aug 2020 Hamid Jalalzai, Rémi Leluc

In the framework of multivariate Extreme Value Theory, a common characterization of extremes' dependence structure is the angular measure.

Asymptotic Analysis of Conditioned Stochastic Gradient Descent

1 code implementation4 Jun 2020 Rémi Leluc, François Portier

In this paper, we investigate a general class of stochastic gradient descent (SGD) algorithms, called Conditioned SGD, based on a preconditioning of the gradient direction.

Control variate selection for Monte Carlo integration

no code implementations26 Jun 2019 Rémi Leluc, François Portier, Johan Segers

Monte Carlo integration with variance reduction by means of control variates can be implemented by the ordinary least squares estimator for the intercept in a multiple linear regression model with the integrand as response and the control variates as covariates.
