Education

  • Master in Computer Science ANDROIDE
    Sorbonne University
    2021
    Le parcours ANDROIDE couvre les thématiques liées à la résolution de problèmes, aux agents, à la décision et à la robotique autonome. Cette formation vise à dispenser un enseignement à la fois théorique et pratique couvrant l'ensemble des principaux domaines de l'Intelligence Artificielle, de la Décision, de la Recherche Opérationnelle et de l'Interaction ; en particulier, elle aborde tous les aspects liés à la « résolution de problèmes » auxquels les acteurs économiques doivent faire face, ainsi que ceux liés à la mise en place de processus d'interaction intelligents, que ce soit avec un utilisateur humain (afin, par exemple, d'acquérir les informations pertinentes à la résolution de problèmes) ou entre entités autonomes, comme des agents artificiels ou des robots. L’essor actuel des outils d’intelligence artificielle, d’aide à la décision et de robotique appelle à la formation d’experts pouvant maîtriser une large palette de techniques, autant symboliques que numériques, et aptes à proposer des solutions innovantes dans leur milieu professionnel, qu’il soit académique ou industriel. L’objectif du parcours est donc de former des spécialistes des STIC (Sciences et Technologies de l'Information et de la Communication), maîtrisant les concepts, modèles et outils (en particulier algorithmiques) de ces thématiques.
  • Bachelor's Degree
