Surrogate modeling with functional nonlinear autoregressive models (F-NARX)
Styfen Schär, Stefano Marelli, Bruno Sudret
We propose a novel functional approach to surrogate modeling of dynamical systems with exogenous inputs. This approach, named Functional Nonlinear AutoRegressive with eXogenous inp…

Uncertainty-aware multi-fidelity surrogate modeling with noisy data
Katerina Giannoukou, Stefano Marelli, Bruno Sudret
Emulating high-accuracy computationally expensive models is crucial for tasks requiring numerous model evaluations, such as uncertainty quantification and optimization. When lower-…

Reliability analysis of arbitrary systems based on active learning and global sensitivity analysis
Maliki Moustapha, Pietro Parisi, Stefano Marelli +1
System reliability analysis aims at computing the probability of failure of an engineering system given a set of uncertain inputs and limit state functions. Active-learning solutio…
