Bayesian Functional Optimization

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2018
Bayesian optimization (BayesOpt) is a derivative-free approach for sequentially optimizing stochastic black-box functions. Standard BayesOpt, which has shown many successes in machine learning applications, assumes a finite dimensional domain which often is a parametric space.

Stratified Bayesian Optimization [PDF]

open access: yes, 2018
We consider derivative-free black-box global optimization of expensive noisy functions, when most of the randomness in the objective is produced by a few influential scalar random inputs. We present a new Bayesian global optimization algorithm, called Stratified Bayesian Optimization (SBO), which uses this strong dependence to improve performance.

Triangulation Candidates for Bayesian Optimization

open access: yesAdvances in Neural Information Processing Systems 35, 2022
Bayesian optimization involves "inner optimization" over a new-data acquisition criterion which is non-convex/highly multi-modal, may be non-differentiable, or may otherwise thwart local numerical optimizers. In such cases it is common to replace continuous search with a discrete one over random candidates.

Bayesian Optimization with Local Search [PDF]

open access: yes, 2020
Global optimization finds applications in a wide range of real world problems. The multi-start methods are a popular class of global optimization techniques, which are based on the ideas of conducting local searches at multiple starting points. In this work we propose a new multi-start algorithm where the starting points are determined in a Bayesian ...

Asynchronous batch Bayesian optimization with pipelining evaluations in experimental equipment-limited situations

open access: yesSLAS Technology
Bayesian optimization is efficient even with a small amount of data and is used in engineering and in science, including biology and chemistry. In Bayesian optimization, a parameterized model with an uncertainty is fitted to explain the experimental data,

Efficient Counterexample Generation for Control Systems Using Multi-Fidelity Bayesian Optimization

open access: yesIEEE Access
Testing controllers in safety-critical systems is vital for ensuring their safety and preventing catastrophic failures. In this paper, we address the falsification problem within closed-loop control systems through simulation.

NUBO: A Transparent Python Package for Bayesian Optimization

open access: yesJournal of Statistical Software
NUBO, short for Newcastle University Bayesian Optimisation, is a Bayesian optimization framework for the optimization of expensive-to-evaluate black-box functions, such as physical experiments and computer simulators.
