WebHyperBO is a framework that pre-trains a Gaussian process and subsequently performs Bayesian optimization with a pre-trained model. With HyperBO, we no longer have to hand-specify the exact quantitative parameters in a Gaussian process. Instead, we only need to identify related tasks and their corresponding data for pre-training.
