Automatic selection for general surrogate models

open access: yesStructural and Multidisciplinary Optimization, 2018
International audienceIn design engineering problems, the use of surro-gate models (also called metamodels) instead of expensive simulations have become very popular. Surrogate models include individual models (regression, kriging, neural network ...) or

Protecting SLAs with surrogate models

Proceedings of the 2nd International Workshop on Principles of Engineering Service-Oriented Systems, 2010
In this paper, we propose the use of surrogate models to avoid or limit violations of the service level agreements (protect SLAs) of enterprise applications executed within virtualized data centers (VDCs).Modern enterprise services are delivered along with service level agreements (SLAs) that formalize the expected quality of service, and define ...

The Surrogate Model

2019
This Chapter presents the first key component of BO, that is, the probabilistic surrogate model. Section 3.1 is focused on Gaussian processes (GPs); Sect. 3.2 introduces the sequential optimization method known as Thompson sampling, also based on GP; finally, Sect. 3.3 presents other probabilistic models which might represent, in some cases, a suitable
