Postdoc research – Habilitation Universitaire 2021 -: 

  • Intelligent systems: Developing architectures based on the deep neural networks  to put more emphasis on user and item interactions when constructing the latent spaces (user-item). In our works, we map the original data to higher order features interactions to achieve more accurate predictions and higher recommendation efficiency. 
  • In Collaboration with: Prof. Hocine Cherifi, Computer science laboratory (LIB), University of Burgundy Franche-Comté, France. 

  • Misinformation detection systems: Building systems which come up with a way of representing the features that are relevant for recognizing information veracity, while at the same time keeping the dimensionality low enough to make the application of machine learning or deep learning computationally feasible. 
  • In Collaboration with: Prof. Refoufi Allaoua, University of Ferhat Abbas, Setif 1, Algeria.  
  • Prof. Silvioa Giordano – Institute of Systems for Informatics and Networking, Switzerland.
