New Gittins Index Method Enhances Cost-Aware Bayesian Optimization

Researchers have developed a novel approach to cost-aware Bayesian optimization by drawing a connection to the Pandora's Box problem from economics. This new method utilizes the Gittins index, typically used for decision-making under uncertainty, as an acquisition function. Empirical results indicate that this Gittins index-based acquisition function performs well, especially in higher dimensions, and its benefits extend to standard Bayesian optimization tasks even without explicit cost considerations.
