"Unsupervised Source Separation with Learned Regularization"

Carloni Gertosio, Rémi

Blind source separation (BSS) algorithms are unsupervised methods that allow for physically meaningful decompositions of multispectral data. Being ill-posed inverse problems, BSS algorithms must rely on efficient regularization schemes to better distinguish between the sources and yield interpretable solutions. For that purpose, we propose a semi-blind source separation approach coined sGMCA in which we combine a projected alternate least-squares algorithm with a learning-based regularization scheme.
