arXiv:2606.00913v1 Announce Type: cross Abstract: Multi-arm bandit algorithms are increasingly used in online platforms, clinical trials, and social science experiments, but valid statistical inference on their performance remains an open challenge. After deploying bandits, a natural question is whether one can construct a confidence interval for its mean reward and assess whether it reliably outperforms a baseline policy. The total reward achieved in any single bandit deployment is random, and deploying a bandit twice on the same population typically yields different reward trajectories due t
This research addresses a growing need for robust statistical methods as multi-arm bandits become ubiquitous in online platforms and various experimental designs, demanding better performance inference.
Improving the ability to construct confidence intervals and assess bandit performance reliably allows for more robust decision-making and optimization in AI-driven systems and experiments.
The ability to accurately quantify the performance and reliability of bandit algorithms will improve, fostering greater trust and more efficient deployment in critical applications.
