Research interests.

    Member of the « Apprentissage, Fusion et Télédétection (AFuTé) thematic » with strong connexions with ReGaRD thematics on distributed systems, HPC, data and ethics,

  • Image, video and more generally data understanding : from data preprocessing, features extraction to concept recognition (objects, action, etc.)  to classical 1D sensors.
  • Heterogeneous Data Fusion : associating multimodal inputs, images, contextual indicators, and others to make the decision process more reliable.
  • Sensor time series in general, from image sequences (multimedia, satellite remote sensing, astrophysics imaging) to classical sensors analysis.
  • Current methodological approaches rely on deep learning methods with some specific directions:
    • Frugal models, low computational cost by design: light architectures efficient in terms of training efficacy as well as reduced inference time.
    • Explainable models, with two approaches:
      • physical aware models design : by introducing physical knowledge in the model structure or by introducing optimization criteria related to the physical phenomenon to be considered.
      • developing XAI visualization techniques to help explain and understand model behaviors and predictions.
    • Physically informed models, ongoing activity
    • Federated learning, distributed and privacy preserving machine learning, ongoing activity.
