Global sensitivity analysis for models with spatially dependent outputs
Amandine Marrel, Bertrand Iooss, Michel Jullien +2
The global sensitivity analysis of a complex numerical model often calls for the estimation of variance-based importance measures, named Sobol' indices. Metamodel-based techniques…

An efficient methodology for modeling complex computer codes with Gaussian processes
Amandine Marrel, Bertrand Iooss, Francois Van Dorpe +1
Complex computer codes are often too time expensive to be directly used to perform uncertainty propagation studies, global sensitivity analysis or to solve optimization problems. A…
