New algorithms ensure replicable dueling bandits with sublinear regret

Researchers have developed new algorithms for replicable dueling bandits, a system where two executions with shared randomness must select the same ordered pair in every round with a high probability. Building on the Beat-the-Mean approach, these algorithms achieve sublinear regret under relaxed stochastic transitivity and the stochastic triangle inequality. For linear dueling bandits, a separate algorithm offers improved regret bounds. Experiments on synthetic data and language model preferences demonstrate the effectiveness of these replicable bandit algorithms. AI
