Regret Lower Bound and Optimal Algorithm for High-Dimensional Contextual Linear Bandit
Ke Li, Yun Yang, Naveen N. Narisetty
In this paper, we consider the multi-armed bandit problem with high-dimensional features. First, we prove a minimax lower bound, $\mathcal{O}\big((\log d)^{\frac{α+1}{2}}T^{\frac{1…

Identifying regions of inhomogeneities in spatial processes via an M-RA and mixture priors
Marco H. Benedetti, Veronica J. Berrocal, Naveen N. Narisetty
Soils have been heralded as a hidden resource that can be leveraged to mitigate and address some of the major global environmental challenges. Specifically, the organic carbon stor…
