Riemannian Geometry for Robust Estimation and Machine Learning

In this topic, the aim is to use the tools of Riemannian geometry to tackle estimation problems with constraints like subspace, structured covariance matrices, ... From these geometries we are able to develop new estimation algorithms as well as new forms of center of classes (useful in machine learning). Moreover, this theory allows to obtain intrinsic Cramer Rao Bound useful to choose a correct metric and distance.

Robust Change Detection and InSAR

In a Satellite Image Time Series, we have developed different robust detectors based on the derivation of the GLRT. The data are assumed to follow a CES distribution and the hypothesis test is built with the scatter matrices, and/or the textures. This work is partially funded by the ANR PHOENIX. We will also be interested in developing robust methods for Interferometry SAR which is actually a covariance problem estimation with a specific structure. This work is funded by ONERA and ANR REPED-SARIX.

Robust Buried Pipe Detection by GPR and person detection in RADAR Through the Wall

In this project, we have to detect buried pipes by a Ground Penetrating Radar. The detectors are derived from the GLRT. The data size is very large and some strategies for the covariance estimation have been proposed. This work has been funded by the FUI g4M.

A new project through an internship and a CIFRE has been begun with the company geolithe. A new robust inversion algorithm has been developed and published in IEEE TGRS. More recently, we adapt deep networks by adding 2nd order statistics which better describe the answers of the scatterers localized into the ground.

We have developed similar works for RADAR Throught the Wall since the data and the problems are very close between these two applications. This work is done by Hugo Brehier (Phd at SONDRA) and co-supervised with Arnaud Breloy (CNAM) and Chengfang Ren (SONDRA)

Multilinear Algebra for RADAR Systems

In this work, we have developed a special multilinear extension of the SVD adapted to STAP and MIMO-STAP configurations.

Random Matrix Theory Tools for RADAR algorithms

In this topic, we have used the Random Matrix Theory tools to derive theoretical approximations of performance of filters and detectors when the disturbance is composed of strong low-rank contribution. Next, we want to propose new low-rank detectors which keep good asymptotic properties in a large dimension regime.

In the same vein, we have developed new low rank change detectors consistent in a high dimensional regime. This is the work of Rémi Beisson with a collaboration with IMS-Univ. de Bordeaux.
