MF-GLaM: A multifidelity stochastic emulator using generalized lambda models
K. Giannoukou, X. Zhu, S. Marelli +1
Stochastic simulators exhibit intrinsic stochasticity due to unobservable, uncontrollable, or unmodeled input variables, resulting in random outputs even at fixed input conditions.…

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…

UQ state-dependent framework for seismic fragility assessment of industrial components
C. Nardin, S. Marelli, O. S. Bursi +2
In this study, we propose a novel surrogate modelling approach to efficiently and accurately approximate the response of complex dynamical systems driven by time-varying Recently,…
