Presentation  &  Research interests

Samy Labsir is a associate professor at IPSA Toulouse (SIA team)  in data science and statistics. At the same time, he carries out research works in statistical signal processing within the laboratory TéSA.  

He obtained its PhD Degree at University of Bordeaux (France),  IMS laboratory,  in the Signal&Image group with collaboration of CEA-CESTA, in December 2020. The title is "Méthodes statistiques fondées sur les groupes de Lie pour le suivi d'un amas de débris spatiaux" and was supervised by Audrey Giremus (Full professor,  HDR, Bordeaux University) and Brice Yver (Engineer, CEA-CESTA).  The associated manuscript is disponible here  and the presentation here.  From October 2020 to November 2022, he was a post-doctoral research assistant at ISAE-SUPAERO (Toulouse, France) in DEOS department, NAVIRRES research group under the supervision of Gael Pages  (Researcher, ISAE-SUPAERO) and Eric Chaumette  (Full professor,  HDR, ISAE-SUPAERO) .  Its research is focused on estimation and machine learning methods for statistical signal processing.  He works on statistical (non)-bayesian methods which use the non-Euclidean properties (Lie groups and Riemannian manifolds) of both unknown parameters and observations.  He also investigates on the development of  (non)-Bayesian error bound for parameters evolved on (non)-Euclidean space (Lie groups).  

Its research works have mainly been built for four main applications : 

• RADAR (change detection with polarimetric SAR, target tracking),

• GNSS  (PVT system, tracking loop, RTK positioning),

• computer vision ( visual-SLAM, point cloud-image registration).
