Small ensembles of kriging models for optimization
CoRR, 2016 The Efficient Global Optimization (EGO) algorithm uses a conditional Gaus-sian Process (GP) to approximate an objective function known at a finite number of observation points and sequentially adds new points which maximize the Expected Improvement criterion according to the GP.

Optimization of Combustion Chamber for Diesel Engine Using Kriging Model
Journal of Fluid Science and Technology, 2006 Diesel engine combustion chamber which reduces exhaust emission has been designed using CFD analysis and optimization techniques. In order to save computational time for design, the Kriging model, one of the response surface models, is adopted here.

Kriging modelization in predicting metal sheet elongation [PDF]
Quality and Reliability Engineering International, 2018 AbstractModern industries are increasingly replacing real experiments with non‐stochastic simulation models due to their restrained costs and growing reliability. The non‐stochastic simulator used in this paper is the Finite Element simulation code (FEM), a widely used numerical technique for the engineering problems modeled by a system of partial ...

Kriging, co-kriging and space mapping for microwave circuit modeling
2011 41st European Microwave Conference, 2011 Space mapping (SM) is a popular technique that allows creating computationally cheap and reasonably accurate surrogates of EM-simulated microwave structures (so-called fine models) using underlying coarse models, typically equivalent circuits. Here, we consider various ways of enhancing SM surrrogates by exploiting additional training data as well as ...

Kriging Models that are Robust with Respect to Simulation Errors [PDF]
SSRN Electronic Journal, 2007 In the field of the Design and Analysis of Computer Experiments (DACE) meta-models are used to approximate time-consuming simulations. These simulations often contain simulation-model errors in the output variables. In the construction of meta-models, these errors are often ignored. Simulation-model errors may be magnified by the meta-model. Therefore,
