New algorithm THV-UCB tackles multi-objective bandit problems

Researchers have introduced a new algorithm called THV-UCB for stochastic multi-objective bandit problems. This algorithm aims to approximate the Pareto frontier by selecting a small set of arms that collectively represent the best trade-offs across multiple objectives. The proposed method establishes theoretical regret bounds, offering support for its application in diverse multi-objective scenarios. AI

    Top-$k$ Pareto Bandits: Hypervolume Regret for Multi-Objective Slate Selection

    arXiv:2607.26273v1 Announce Type: cross Abstract: We consider a stochastic multi-objective bandit problem where, at each round, the agent selects a slate of $k$ arms and observes their $d$-dimensional reward vectors under semi-bandit feedback. We do not aim at identifying a singl…
