Active multiple matrix completion with adaptive confidence sets
Andrea Locatelli, Alexandra Carpentier, Michal Valko
In this work, we formulate a new multi-task active learning setting in which the learner's goal is to solve multiple matrix completion problems simultaneously. At each round, the l…
An Adaptive Strategy for Active Learning with Smooth Decision Boundary
Andrea Locatelli, Alexandra Carpentier, Samory Kpotufe
We present the first adaptive strategy for active learning in the setting of classification with smooth decision boundary. The problem of adaptivity (to unknown distributional para…
Adaptivity to Noise Parameters in Nonparametric Active Learning
Andrea Locatelli, Alexandra Carpentier, Samory Kpotufe
This work addresses various open questions in the theory of active learning for nonparametric classification. Our contributions are both statistical and algorithmic: -We establish…
Tight (Lower) Bounds for the Fixed Budget Best Arm Identification Bandit Problem
Alexandra Carpentier, Andrea Locatelli
We consider the problem of \textit{best arm identification} with a \textit{fixed budget }, in the -armed stochastic bandit setting, with arms distribution defined on .…
An optimal algorithm for the Thresholding Bandit Problem
Andrea Locatelli, Maurilio Gutzeit, Alexandra Carpentier
We study a specific \textit{combinatorial pure exploration stochastic bandit problem} where the learner aims at finding the set of arms whose means are above a given threshold, up…
