Estimation of the -norm and testing in sparse linear regression with unknown variance
Alexandra Carpentier, Olivier Collier, Laetitia Comminges +2
We consider the related problems of estimating the -norm and the squared -norm in sparse linear regression with unknown variance, as well as the problem of testing the hy…
The Elliptical Potential Lemma Revisited
Alexandra Carpentier, Claire Vernade, Yasin Abbasi-Yadkori
This note proposes a new proof and new perspectives on the so-called Elliptical Potential Lemma. This result is important in online learning, especially for linear stochastic bandi…
Stochastic bandits with arm-dependent delays
Anne Gael Manegueu, Claire Vernade, Alexandra Carpentier +1
Significant work has been recently dedicated to the stochastic delayed bandit setting because of its relevance in applications. The applicability of existing algorithms is however…
The Influence of Shape Constraints on the Thresholding Bandit Problem
James Cheshire, Pierre Menard, Alexandra Carpentier
We investigate the stochastic Thresholding Bandit problem (TBP) under several shape constraints. On top of (i) the vanilla, unstructured TBP, we consider the case where (ii) the se…
