Logarithmic weak regret of non-Bayesian restless multi-armed bandit
Abstract—We consider the restless multi-armed bandit (RMAB) problem with unknown dynamics. At each time, a player chooses K out of N (N > K) arms to play. The state of each ar...

Emergence of rationality amongst simple nodes performing adaptive filtering
We present a decentralized adaptive filtering algorithm where each agent acts selfishly to maximize its payoff. Agents are only aware of the actions of other agents within their...
