Bayesian Optimization
■ Leveraging Bayesian optimization to improve regression models
▲ Flowchart of the Bayesian optimization
(expected improvement is used for the acquisition function)
■ Different queries during Bayesian optimization due to uncertainty calibration process
▲ After uncertainty calibration, different exploration characteristics can be observed
(after calibration, much stronger exploratory tendency w.r.t. input variable δr is shown)
