A supermartingale approach to Gaussian process based sequential design of experiments

J Bect, F Bachoc, D Ginsbourger - 2019 - projecteuclid.org
Gaussian process (GP) models have become a well-established framework for the adaptive
design of costly experiments, and notably of computer experiments. GP-based sequential …

Quantifying uncertainty on Pareto fronts with Gaussian process conditional simulations

M Binois, D Ginsbourger, O Roustant - European journal of operational …, 2015 - Elsevier
Multi-objective optimization algorithms aim at finding Pareto-optimal solutions. Recovering
Pareto fronts or Pareto sets from a limited number of function evaluations are challenging …

Reliability analysis and optimal design under uncertainty-Focus on adaptive surrogate-based approaches

JM Bourinet - 2018 - theses.hal.science
The design of optimal and reliable systems is an objective which is pursued in several fields
of engineering. Optimality is expressed in terms of a system cost which needs to be …

Differentiating the multipoint expected improvement for optimal batch design

S Marmin, C Chevalier, D Ginsbourger - International workshop on …, 2015 - Springer
This work deals with parallel optimization of expensive objective functions which are
modelled as sample realizations of Gaussian processes. The study is formalized as a …

Adaptive design of experiments for conservative estimation of excursion sets

D Azzimonti, D Ginsbourger, C Chevalier, J Bect… - …, 2021 - Taylor & Francis
We consider the problem of estimating the set of all inputs that leads a system to some
particular behavior. The system is modeled by an expensive-to-evaluate function, such as a …

Multi-robot learning and coverage of unknown spatial fields

M Santos, U Madhushani, A Benevento… - … Symposium on Multi …, 2021 - ieeexplore.ieee.org
This paper addresses the problem of optimally covering a domain when the scalar function
that describes the relative importance of the points in the domain is initially unknown. We …

Rare Event Detection by Acquisition-Guided Sampling

H Liao, X Qian, JZ Huang, P Li - IEEE Transactions on …, 2024 - ieeexplore.ieee.org
Motivated by the challenges in detecting extremely rare failures for sophisticated
specifications in circuit design, we consider the problem of detecting regions of interest …

A new expected-improvement algorithm for continuous minimax optimization

J Marzat, E Walter, H Piet-Lahanier - Journal of Global Optimization, 2016 - Springer
Worst-case design is important whenever robustness to adverse environmental conditions
must be ensured regardless of their probability. It leads to minimax optimization, which is …

A sampling criterion for constrained Bayesian optimization with uncertainties

RE Amri, RL Riche, C Helbert… - arxiv preprint arxiv …, 2021 - arxiv.org
We consider the problem of chance constrained optimization where it is sought to optimize a
function and satisfy constraints, both of which are affected by uncertainties. The real world …

Evaluating Gaussian process metamodels and sequential designs for noisy level set estimation

X Lyu, M Binois, M Ludkovski - Statistics and Computing, 2021 - Springer
We consider the problem of learning the level set for which a noisy black-box function
exceeds a given threshold. To efficiently reconstruct the level set, we investigate Gaussian …
