Domain-Aware Augmentations for Unsupervised Online General Continual Learning

no code implementations13 Sep 2023 Nicolas Michel, Romain Negrel, Giovanni Chierchia, Jean-François Bercher

Continual Learning has been challenging, especially when dealing with unsupervised scenarios such as Unsupervised Online General Continual Learning (UOGCL), where the learning agent has no prior knowledge of class boundaries or task change information.

New metrics for analyzing continual learners

no code implementations1 Sep 2023 Nicolas Michel, Giovanni Chierchia, Romain Negrel, Jean-François Bercher, Toshihiko Yamasaki

This scenario, known as Continual Learning (CL) poses challenges to standard learning algorithms which struggle to maintain knowledge of old tasks while learning new ones.

Online convex optimization and no-regret learning: Algorithms, guarantees and applications

no code implementations12 Apr 2018 E. Veronica Belmega, Panayotis Mertikopoulos, Romain Negrel, Luca Sanguinetti

Spurred by the enthusiasm surrounding the "Big Data" paradigm, the mathematical and algorithmic tools of online optimization have found widespread use in problems where the trade-off between data exploration and exploitation plays a predominant role.
