New framework unifies bandit problem objectives

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a new framework called TG-ITE to address multiple objectives in stochastic dueling bandits. This unified approach aims to simultaneously optimize best-arm identification and minimize both weak and strong regret. TG-ITE achieves this by first identifying a strong candidate arm using a tree-guided method and then employing specific exploitation strategies for each objective, offering improved sample complexity and joint optimization capabilities.

    Tree-Guided Identify-Then-Exploit: A Unified Framework of Best Arm Identification and Regret Minimization for Dueling Bandits

    arXiv:2606.01799v1 Announce Type: cross Abstract: We study $N$-armed stochastic dueling bandits under the Condorcet-winner assumption, where three widely adopted objectives are considered: best-arm identification (BAI), weak regret, and strong regret. We propose Tree-Guided Ident…
