Researchers have developed a new Thompson Sampling approach for Bayesian optimization that utilizes preferential feedback, such as pairwise comparisons, instead of scalar scores. This method models comparisons through a monotone link on latent utility differences and employs a dueling kernel. A finite-time analysis demonstrates that this approach achieves performance comparable to standard Thompson Sampling used with scalar feedback. AI
