Global sensitivity analysis using derivative-based sparse Poincaré chaos expansions
Nora Lüthen, Olivier Roustant, Fabrice Gamboa +3
Variance-based global sensitivity analysis, in particular Sobol' analysis, is widely used for determining the importance of input variables to a computational model. Sobol' indices…
Rare event estimation using stochastic spectral embedding
P. -R. Wagner, S. Marelli, I. Papaioannou +2
Estimating the probability of rare failure events is an essential step in the reliability assessment of engineering systems. Computing this failure probability for complex non-line…
Sequential active learning of low-dimensional model representations for reliability analysis
Max Ehre, Iason Papaioannou, Bruno Sudret +1
To date, the analysis of high-dimensional, computationally expensive engineering models remains a difficult challenge in risk and reliability engineering. We use a combination of d…
Active learning for structural reliability: survey, general framework and benchmark
M. Moustapha, S. Marelli, B. Sudret
Active learning methods have recently surged in the literature due to their ability to solve complex structural reliability problems within an affordable computational cost. These…
