Online Learning of Weakly Coupled MDP Policies for Load Balancing and Auto Scaling

1 code implementation20 Jun 2024 S. R. Eshwar, Lucas Lopes Felipe, Alexandre Reiffers-Masson, Daniel Sadoc Menasché, Gugan Thoppe

Load balancing and auto scaling are at the core of scalable, contemporary systems, addressing dynamic resource allocation and service rate adjustments in response to workload changes.

A Practical Approach to Novel Class Discovery in Tabular Data

2 code implementations9 Nov 2023 Colin Troisemaine, Alexandre Reiffers-Masson, Stéphane Gosselin, Vincent Lemaire, Sandrine Vaton

In particular, the number of novel classes is usually assumed to be known in advance, and their labels are sometimes used to tune hyperparameters.

Online Learning with Adversaries: A Differential-Inclusion Analysis

no code implementations4 Apr 2023 Swetha Ganesh, Alexandre Reiffers-Masson, Gugan Thoppe

Our main result is that the proposed algorithm almost surely converges to the desired mean $\mu.$ This makes ours the first asynchronous FL method to have an a. s. convergence guarantee in the presence of adversaries.

Novel Class Discovery: an Introduction and Key Concepts

2 code implementations22 Feb 2023 Colin Troisemaine, Vincent Lemaire, Stéphane Gosselin, Alexandre Reiffers-Masson, Joachim Flocon-Cholet, Sandrine Vaton

We then give an overview of the different families of approaches, organized by the way they transfer knowledge from the labeled set to the unlabeled set.

Contrastive Learning Novel Class Discovery +1

Découvrir de nouvelles classes dans des données tabulaires

1 code implementation28 Nov 2022 Colin Troisemaine, Joachim Flocon-Cholet, Stéphane Gosselin, Sandrine Vaton, Alexandre Reiffers-Masson, Vincent Lemaire

In Novel Class Discovery (NCD), the goal is to find new classes in an unlabeled set given a labeled set of known but different classes.

Geometry-preserving Lie Group Integrators For Differential Equations On The Manifold Of Symmetric Positive Definite Matrices

no code implementations17 Oct 2022 Lucas Drumetz, Alexandre Reiffers-Masson, Naoufal El Bekri, Franck Vermet

The application of Euclidean methods to integrate differential equations lying on such objects does not respect the geometry of the manifold, which can cause many numerical issues.

Online Multi-Agent Decentralized Byzantine-robust Gradient Estimation

no code implementations30 Sep 2022 Alexandre Reiffers-Masson, Isabel Amigo

In this paper, we propose an iterative scheme for distributed Byzantineresilient estimation of a gradient associated with a black-box model.
