Screening and metamodeling of computer experiments with functional outputs. Application to thermal-hydraulic computations
Benjamin Auder, Agnes De Crecy, Bertrand Iooss +1
To perform uncertainty, sensitivity or optimization analysis on scalar variables calculated by a cpu time expensive computer code, a widely accepted methodology consists in first i…
Group Lasso estimation of high-dimensional covariance matrices
Jérémie Bigot, Rolando Biscay, Jean-Michel Loubes +1
In this paper, we consider the Group Lasso estimator of the covariance matrix of a stochastic process corrupted by an additive noise. We propose to estimate the covariance matrix i…
Adaptive non-asymptotic confidence balls in density estimation
Matthieu Lerasle
We build confidence balls for the common density of a real valued sample . We use resampling methods to estimate the projection of onto finite dimensional line…
Clustering and variable selection for categorical multivariate data
Dominique Bontemps, Wilson Toussile
This article investigates unsupervised classification techniques for categorical multivariate data. The study employs multivariate multinomial mixture modeling, which is a type of…
