Computer code validation via mixture model estimation
Negar Soleimani, Pierre Barbillon, Kaniav Kamary +1
When computer codes model complex physical systems, calibration alone is insufficient; one must also assess whether a discrepancy term is needed. In this paper, we study computer c…
Bayesian Optimization for reanalysis and calibration of highly energetic sea state events simulated with a spectral third-generation wave model
Cédric Goeury, Thierry Fouquet, Maria Teles +1
Accurate hindcasting of sea state events is a cornerstone of coastal engineering, risk assessment, and climate-related studies, yet it remains limited by uncertainties in physical…
Evaluating the effects of preprocessing, method selection, and hyperparameter tuning on SAR-based flood mapping and water depth estimation
Jean-Paul Travert, Cédric Goeury, Sébastien Boyaval +2
Flood mapping and water depth estimation from Synthetic Aperture Radar (SAR) imagery are crucial for calibrating and validating hydraulic models. This study uses SAR imagery to eva…
A tree-based Polynomial Chaos expansion for surrogate modeling and sensitivity analysis of complex numerical models
Faten Ben Said, Aurélien Alfonsi, Anne Dutfoy +4
This paper introduces Tree-based Polynomial Chaos Expansion (Tree-PCE), a novel surrogate modeling technique designed to efficiently approximate complex numerical models exhibiting…
Evaluation of Performance Measures for Qualifying Flood Models with Satellite Observations
Jean-Paul Travert, Sébastien Boyaval, Cédric Goeury +2
This work discusses how to choose performance measures to compare numerical simulations of a flood event with one satellite image, e.g., in a model calibration or validation proced…
Surrogate-based variational data assimilation for tidal modelling
Rem-Sophia Mouradi, Cédric Goeury, Olivier Thual +2
Data assimilation (DA) is widely used to combine physical knowledge and observations. It is nowadays commonly used in geosciences to perform parametric calibration. In a context of…
Interoperability and computational framework for simulating open channel hydraulics: application to sensitivity analysis and calibration of Gironde Estuary model
Cedric Goeury, Yoann Audouin, Fabrice Zaoui
Water resource management is of crucial societal and economic importance, requiring a strong capacity for anticipating environmental change. Progress in physical process knowledge,…
Physically interpretable machine learning algorithm on multidimensional non-linear fields
Rem-Sophia Mouradi, Cédric Goeury, Olivier Thual +2
In an ever-increasing interest for Machine Learning (ML) and a favorable data development context, we here propose an original methodology for data-based prediction of two-dimensio…
A Metamodel of the Telemac Errors
Fabrice Zaoui, Cédric Goeury, Yoann Audouin
A Telemac study is a computationally intensive application for the real cases and in the context of quantifying or optimizing uncertainties, the running times can be too long. This…
