Transmutation techniques and observability for time-discrete approximation schemes of conservative systems
Sylvain Ervedoza, Enrique Zuazua
In this article, we consider abstract linear conservative systems and their time-discrete counterparts. Our main result is a representation formula expressing solutions of the cont…
Sensitivity indices for multivariate outputs
Fabrice Gamboa, Alexandre Janon, Thierry Klein +1
We define and study a generalization of Sobol sensitivity indices for the case of a vector output.
General regularization schemes for signal detection in inverse problems
Clément Marteau, Peter Mathé
The authors discuss how general regularization schemes, in particular linear regularization schemes and projection schemes, can be used to design tests for signal detection in stat…
Shape invariant model approach for functional data analysis in uncertainty and sensitivity studies
Ekaterina Sergienko, Fabrice Gamboa, Daniel Busby
Dynamic simulators model systems evolving over time. Often, it operates iteratively over fixed number of time-steps. The output of such simulator can be considered as time series o…
Reliability sensitivity analysis based on probability distribution perturbation with application to CO2 storage
Ekaterina Sergienko, Paul Lemaître, Aurélie Arnaud +2
The objective of reliability sensitivity analysis is to determine input variables that mostly contribute to the variability of the failure probability. In this paper, we study a re…
Statistical inference for Sobol pick freeze Monte Carlo method
Fabrice Gamboa, Alexandre Janon, Thierry Klein +2
Many mathematical models involve input parameters, which are not precisely known. Global sensitivity analysis aims to identify the parameters whose uncertainty has the largest impa…
