Harnessing new information in Bayesian optimization


This seminar delves into two key advancements that contribute to the capabilities of Bayesian optimization methods. We first focus on a novel information-theoretical acquisition function called joint entropy search (JES) which introduces a new quantity to improve statistical efficiency. We then explore the integration of active learning techniques and propose self-correcting Bayesian optimization (SCoreBO) which consciously learns the model hyperparameters while optimizing the black-box function. We emphasize the benefits of adaptively selecting informative data points and address the challenges related to model misspecification.
