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-…
pyFFS: A Python Library for Fast Fourier Series Computation and Interpolation with GPU Acceleration
Eric Bezzam, Sepand Kashani, Paul Hurley +2
Fourier transforms are an often necessary component in many computational tasks, and can be computed efficiently through the fast Fourier transform (FFT) algorithm. However, many a…
SiML: Sieved Maximum Likelihood for Array Signal Processing
Matthieu Simeoni, Paul Hurley
Stochastic Maximum Likelihood (SML) is a popular direction of arrival (DOA) estimation technique in array signal processing. It is a parametric method that jointly estimates signal…
