Scalarizing cost-effective multiobjective optimization algorithms made possible with kriging
, 2007 The use of kriging in cost-effective single-objective optimization is well established, and a wide variety of different criteria now exist for selecting design vectors to evaluate in the search for the global minimum.

A Novel Combination Co-Kriging Model Based on Gaussian Random Process
Mathematical Problems in Engineering, 2018 Co-Kriging (CK) modeling provides an efficient way to predict responses of complicated engineering problems based on a set of sample data obtained by methods with varying degree of accuracy and computation cost. In this work, the Gaussian random process (GRP) is introduced to construct a novel combination CK model (CK-GRP) to improve the prediction ...

A partial envelope approach for modelling multivariate spatial‐temporal data
Canadian Journal of Statistics, EarlyView.Abstract In the new era of big data, modelling multivariate spatial‐temporal data is a challenging task due to both the high dimensionality of the features and complex associations among the responses across different locations and time points.

OPTIMIZATION OF MULTI-FIDELITY DATA USING CO-KRIGING FOR HIGH DIMENSIONAL PROBLEMS [PDF]
The International Conference on Applied Mechanics and Mechanical Engineering, 2014 ABSTRACTThis paper deals with an efficient and multi-fidelity design strategy for high dimensional industrial problems. The most significant factors have been determined based on the Muschelknautz method of modeling (MM) using the screening approach. For cyclone separator, only four (from seven) geometrical parameters are significant.

Assessing the Spatial Distribution of Rainfall and the Effect of Altitude in Iran (Hamadan Province)
Air, Soil and Water Research, 2017 Atmospheric phenomena have an enormous influence on natural resources and human life. Lack of sufficient information and knowledge in regard to the management of natural areas and ecosystems will bring about a huge cost. Hamadan province according to the

Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Failure Probability Assessment using co-Kriging Surrogate Models
Procedia Engineering, 2015 Abstract Industries, among them the aeronautics industry, have to justify the reliability of the structures they design. Static and modal analyzes are the classical methods to validate designs. Nowadays, these are not sufficient anymore, and the damage tolerance approaches, characterizing the severity of a flaw occurring in the designed assembly, are
