Bayesian optimization is a heuristic approach that is applicable to low-dimensional optimization problems. Since it avoids using gradient information altogether, it is a popular approach for …
What is a good way to judge the ‘goodness’ of hyperparameters in Gaussian process regression and Bayesian linear regression? How to judge whether the predicted amount of ‘uncertainty’ is …
Two major design decisions for Bayesian optimization: The prior: the probability distribution over functions that we use. This encodes our assumptions about the function f. – The standard way …
Review of Gaussian process priors! ‣ Bayesian optimization basics! ‣ Managing covariances and kernel parameters! ‣ Accounting for the cost of evaluation! ‣ Parallelizing training! ‣ Sharing …
Gaussian Processes and Bayesian Optimization
Sep 4, 2020 · Nonstationary GP models in computer experiments IV. Bayesian optimization. In supervised learning (e.g., classification and regression) we want to find the underlying function …
Information Directed Sampling: Bayesian optimization with heteroscedastic noise; including theoretical guarantees. Thanks to Felix Berkenkamp for sharing his python notebooks.
In Bayesian Optimization we maintain a particular belief bt = P (f | D), namely a Gaussian Process, and choose the next query based on that. A function is an infinite dimensional thing – …

We propose a process design method based on adaptive design of experiments and Bayesian optimization. Optimization of X values that satisfy target values of multiple Y variables are …
Using a chemical process optimization case study, we benchmark the effectiveness of BOIS against standard BO and sampling approaches. Our results indicate that BOIS achieves …
