Science project

The science project of the MATRIX (Models and AlgoriThms for pRocessIng and eXtracting information) team is to develop new methods to learn, model and understand temporally and spatially structured information (signals, images, time series). These methods will be designed with optimality and performance in mind.


Who are we?

The members of the MATRIX team consists of members drawn from various scientific fields (signal processing, control and command, optimization) and have significant experience in various application domains. They share the observation that it is necessary to develop new generic methods to overcome the technological barriers posed by the applications.

The MATRIX team members are located at IMT Atlantique and ENSTA Bretagne and consists of   :

  • 3 full professors HDR
  • 4 associate professors
  • 1 research engineer
  • 3 post-doctoral researchers
  • 14 PhD students

Scientific objectives

  • developing data-driven and model-driven methods
  • combining physical, dynamic and/or statistical models with data-driven models
  • solving sparse and global optimization problems

Academic expertise

  • information processing: signal, image, video, unstructured data
  • machine learning
  • control of uncertain dynamic systems
  • physical, Bayesian and non-Bayesian modeling
  • sparsity
  • continuous and global optimisation
  • inverse problems

Examples of applications

  • network metrology
  • detection and localization in urban environment by HF radar
  • design of sensor networks and optimization of their placement by compressed sensing
  • characterization of soil salinity from time series of satellite images
  • estimation and tracking of acoustic parameters of the underwater environment
  • cetacean detection and tracking
  • seafloor characterization from sonar data
  • seismic data processing
  • robust control of underwater robots
  • mathematical theory of resilience
