14h00-15h00 – Salle du conseil (L2S) Riemannian geometry for data analysis: illustration on blind source separation and low-rank structured covariance matrices Florent Bouchard (Chargé de recherche CNRS, L2S, CentraleSupélec) Abstract. In this presentation, Riemannian geometry for data analysis is introduced. In particular, it is applied on two specific statistical signal processing problems: blind source separation […]
