    • Knowledge Based Diagnostic System With Probabilistic Approach 

      Cocu, Adina ("Dunarea de Jos" University of Galati, 2007)
      This paper presents a knowledge learning diagnostic approach implemented in an educational system. Probabilistic inference is used here to diagnose knowledge understanding level and to reason about probable cause of learner’s ...

    • Learning Bayesian Dependence Model for Student Modelling 

      Cocu, Adina ("Dunarea de Jos" University of Galati, 2008)
      Learning a Bayesian network from a numeric set of data is a challenging task because of dual nature of learning process: initial need to learn network structure, and then to find out the distribution probability tables. ...

    • Pedagogical Knowledge Model Based on Conceptual Graphs and Ontology 

      Ştefănescu, Diana; Pecheanu, Emilia; Cocu, Adina ("Dunarea de Jos" University of Galati, 2005)
      Intelligent educational systems are knowledge-based systems (KBS) they can be developed by a generic knowledge-based system development methodology. In this paper, we present an ontology-based approach for formalizing ...

    • Possibilistic Networks for Uncertainy Knowledge Processing in Student Diagnosis 

      Cocu, Adina ("Dunarea de Jos" University of Galati, 2006)
      In this paper, a possibilistic network implementation for uncertain knowledge modeling of the diagnostic process is proposed as a means to achieve student diagnosis in intelligent tutoring system. This approach is proposed ...

    • Uncertainty Management Using Bayesian Networks in Student Knowledge Diagnosis 

      Cocu, Adina; Ştefănescu, Diana ("Dunarea de Jos" University of Galati, 2005)
      In intelligent tutoring systems, student or user modeling implies dealing with imperfect and uncertain knowledge. One of the artificial intelligence techniques used for uncertainty management is that of Bayesian networks. ...
