Proximal Multitask Learning over Networks with Sparsity-inducing Coregularization
Roula Nassif, Cédric Richard, André Ferrari +1
In this work, we consider multitask learning problems where clusters of nodes are interested in estimating their own parameter vector. Cooperation among clusters is beneficial when…
Distributed image reconstruction for very large arrays in radio astronomy
André Ferrari, David Mary, Rémi Flamary +1
Current and future radio interferometric arrays such as LOFAR and SKA are characterized by a paradox. Their large number of receptors (up to millions) allow theoretically unprecede…
Multi-frequency image reconstruction for radio interferometry. A regularized inverse problem approach
André Ferrari, Jérémy Deguignet, Chiara Ferrari +3
We describe a "spatio-spectral" deconvolution algorithm for wide-band imaging in radio interferometry. In contrast with the existing multi-frequency reconstruction algorithms, the…
Large Scale 3D Image Reconstruction in Optical Interferometry
Antony Schutz, André Ferrari, David Mary +2
Astronomical optical interferometers (OI) sample the Fourier transform of the intensity distribution of a source at the observation wavelength. Because of rapid atmospheric perturb…
