Computer Science

Maximum Weight Entropy

This paper deals with uncertainty quantification and out-of-distribution detection in deep learning using Bayesian and ensemble methods. It proposes a practical solution to the lack of prediction diversity observed recently for standard approaches…

Machine Learning

Conformal Approach To Gaussian Process Surrogate Evaluation With Coverage Guarantees

Gaussian processes (GPs) are a Bayesian machine learning approach widely used to construct surrogate models for the uncertainty quantification of computer simulation codes in industrial applications. It provides both a mean predictor and an estimate…

Sensitivity Analyses of a Multi-Physics Long-Term Clogging Model For Steam Generators

Long-term operation of nuclear steam generators can result in the occurrence of clogging, a deposition phenomenon that may increase the risk of mechanical and vibration loadings on tube bundles and internal structures as well as potentially…

Towards high-performance linear potential flow BEM solver with low-rank compressions

The interaction of water waves with floating bodies can be modelled with linear potential flow theory, numerically solved with the Boundary Element Method (BEM). This method requires the construction of dense matrices and the resolution of the…

Non-resonant inelastic X-ray scattering for discrimination of pigments

Inelastic X-ray scattering spectroscopy (IXS) has been used in many fields of solid state physics and theoretical chemistry as an accurate and quantitative probe of elementary excitations. We show that IXS spectra in the energy loss range below 100…
