The Role of Coordinates in Pareto Regret for Adversarial Multi-Objective Bandits
Changkun Guan, Mengfan Xu
Adversarial multi-objective bandits hold the potential to help us optimize choices (arms) whose reward is a multidimensional vector chosen by an adversary and whose performance is…

Are Stochastic Multi-objective Bandits Harder than Single-objective Bandits?
Changkun Guan, Mengfan Xu
Multi-objective bandits have attracted increasing attention for their broad applicability, with \(d\)-dimensional reward vectors inducing Pareto regret. There has been a subtle deb…
