A model for efficient dynamical ranking in networks

no code implementations25 Jul 2023 Andrea Della Vecchia, Kibidi Neocosmos, Daniel B. Larremore, Cristopher Moore, Caterina De Bacco

We present a physics-inspired method for inferring dynamic rankings in directed temporal networks - networks in which each directed and timestamped edge reflects the outcome and timing of a pairwise interaction.

Snacks: a fast large-scale kernel SVM solver

no code implementations17 Apr 2023 Sofiane Tanji, Andrea Della Vecchia, François Glineur, Silvia Villa

Kernel methods provide a powerful framework for non parametric learning.

Regularized ERM on random subspaces

no code implementations4 Dec 2022 Andrea Della Vecchia, Ernesto de Vito, Lorenzo Rosasco

We study a natural extension of classical empirical risk minimization, where the hypothesis space is a random subspace of a given space.

AdaTask: Adaptive Multitask Online Learning

no code implementations31 May 2022 Pierre Laforgue, Andrea Della Vecchia, Nicolò Cesa-Bianchi, Lorenzo Rosasco

We introduce and analyze AdaTask, a multitask online learning algorithm that adapts to the unknown structure of the tasks.
