Distributed Learning over Markovian Fading Channels for Stable Spectrum Access
Tomer Gafni, Kobi Cohen
We consider the problem of multi-user spectrum access in wireless networks. The bandwidth is divided into K orthogonal channels, and M users aim to access the spectrum. Each user c…

Searching for Anomalies over Composite Hypotheses
Bar Hemo, Tomer Gafni, Kobi Cohen +1
The problem of detecting anomalies in multiple processes is considered. We consider a composite hypothesis case, in which the measurements drawn when observing a process follow a c…

Learning in Restless Multi-Armed Bandits via Adaptive Arm Sequencing Rules
Tomer Gafni, Kobi Cohen
We consider a class of restless multi-armed bandit (RMAB) problems with unknown arm dynamics. At each time, a player chooses an arm out of N arms to play, referred to as an active…
