Functional Estimation of Anisotropic Covariance and Autocovariance Operators on the Sphere
Alessia Caponera, Julien Fageot, Matthieu Simeoni +1
We propose nonparametric estimators for the second-order central moments of possibly anisotropic spherical random fields, within a functional data analysis context. We consider a m…

A Fast and Scalable Polyatomic Frank-Wolfe Algorithm for the LASSO
Adrian Jarret, Julien Fageot, Matthieu Simeoni
We propose a fast and scalable Polyatomic Frank-Wolfe (P-FW) algorithm for the resolution of high-dimensional LASSO regression problems. The latter improves upon traditional Frank-…
