Global sensitivity analysis in probabilistic graphical models
CoRR, 2021 We show how to apply Sobol's method of global sensitivity analysis to measure the influence exerted by a set of nodes' evidence on a quantity of interest expressed by a Bayesian network. Our method exploits the network structure so as to transform the problem of Sobol index estimation into that of marginalization inference. This way, we can efficiently

Global Sensitivity Analysis for the Linear Assignment Problem [PDF]
2020 American Control Conference (ACC), 2020 In this paper, the following question is addressed: given a linear assignment problem, how much can the all of the individual assignment weights be perturbed without changing the optimal assignment? The extension of results involving perturbations in just one edge or one row/column are presented.

Global Sensitivity Analysis of a Microbial Fuel Cell Model
International Journal of Electrochemical Science, 2019 The global sensitivity method based on variance was applied to the microbial fuel cell (MFC) field for the first time here. The purpose of this study was to expound how the global sensitivity method can be used in the mathematical model of MFC and to ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Hemophilic arthropathy remains the leading morbidity in hemophilia despite modern prophylaxis, and early joint damage may be missed by routine exams. This study explored T2* MRI as a noninvasive biomarker of hemosiderin deposition in pediatric hemophilia.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Acute lymphoblastic leukaemia (ALL) is one of the most treatable forms of paediatric cancer; however, there is a substantial burden of treatment‐related toxicities (TRTs). In addition, the long‐term changes in children's health‐related quality of life (HRQoL) due to toxic treatments are not well understood.

Generalized global sensitivity and correlation analysis
Information and Control, 1980 Quantities measuring sensitivities and correlations of parameters involved in an engineering system are systematically defined by means of lattice theory. Consideration of lattice duality leads to recognition of polymatroid structure of the sensitivity and correlation measures.

Optimizing Genetic Circuits by Global Sensitivity Analysis [PDF]
Biophysical Journal, 2004 Artificial genetic circuits are becoming important tools for controlling cellular behavior and studying molecular biosystems. To genetically optimize the properties of complex circuits in a practically feasible fashion, it is necessary to identify the best genes and/or their regulatory components as mutation targets to avoid the mutation experiments ...

Global sensitivity analysis of rare event probabilities
CoRR, 2021 By their very nature, rare event probabilities are expensive to compute; they are also delicate to estimate as their value strongly depends on distributional assumptions on the model parameters. Hence, understanding the sensitivity of the computed rare event probabilities to the hyper-parameters that define the distribution law of the model parameters ...

Towards global sensitivity analysis of large-scale flood loss models [PDF]
Natural Hazards and Earth System SciencesFlood loss models are increasingly used in the (re)insurance sector to inform a range of financial decisions, and more broadly in research and policy analysis to understand present-day and future flood risk trends.
