Metamodel-based methodology for uncertainty propagation and global sensitivity analysis of tailings dam-breach flows

Yuri Taglieri Sáo, Geraldo de Freitas Maciel, Julian Cardoso Eleutério

Tailings dam-breach analyses are essential for flood-hazard assessment, emergency planning and risk estimation, but their results are strongly affected by uncertainties in breach d…

Estimation and model errors in Gaussian-process-based Sensitivity Analysis of functional outputs

Yuri Taglieri Sáo, Olivier Roustant, Geraldo de Freitas Maciel

Global sensitivity analysis (GSA) of functional-output models is usually performed by combining statistical techniques, such as basis expansions, metamodeling and sampling based es…

Fast pick-freeze estimation of Sobol' sensitivity maps using basis expansions

Yuri Sao, Olivier Roustant, Geraldo de Freitas Maciel

Global sensitivity analysis (GSA) aims at quantifying the contribution of input variables over the variability of model outputs. In the frame of functional outputs, a common goal i…
