New framework unifies bandit problem objectives

By PulseAugur Editorial · [2 sources] ·

Researchers have introduced a new framework called Tree-Guided Identify-Then-Exploit (TG-ITE) to address multiple objectives in stochastic dueling bandits. This unified approach aims to simultaneously optimize best-arm identification (BAI) and minimize both weak and strong regret. TG-ITE achieves this by first identifying a high-confidence incumbent arm and then employing tailored exploitation strategies for specific goals, 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…
