    • A posteriori knowledge: from ambiguous knowledge or undefined information to knowledge 

      Alvarado Mentado, Matías (1994-11)
      External research report
      Open Access
      Incomplete worlds or ambiguous actions are topics that encourage research in theories about reasoning and action (Brewka and Hertzberg 1993). Driankov's model-based approaches propose to deal with the problem using Belnap's ...
    • About the attribute relevance's nature 

      Núñez Esquer, Gustavo; Cortés García, Claudio Ulises; Belanche Muñoz, Luis Antonio; Alvarado Mentado, Matías (1991-03)
      External research report
      Open Access
      The notion of relevance of an attribute in machine learning is of common use in the construction of classfication rules in inductive learning processes. In this work a formal definition of the relevance concept for a given ...
    • An approach to belief in strong Kleene logic 

      Núñez Esquer, Gustavo; Alvarado Mentado, Matías (1995-06)
      External research report
      Open Access
      Three-valued Strong Kleene Logic provides an adequate framework to deal with belief change. In this paper, an undefined truth-value is used to denote opinionless information. Through an informative refinement, such information ...
    • Conocimiento en mundos posibles mediante una relación de posibilidad constructiva 

      Alvarado Mentado, Matías (1993-09)
      External research report
      Open Access
      In the logics of belief, the possible worlds semantic (Kripke 59) is attractive, for its formal elegance and for the intuitive notion of making a discourse, not only of the present world but for any possible world. The ...
    • Relative knowledge and belief: SKL preferred model frames 

      Alvarado Mentado, Matías (1994-02)
      External research report
      Open Access
      The partial SKL**-logic, defined by P. Doherty in A Three-Valued Approach to Non-Monotonic Reasoning (1990) is based upon the three valued logic of S.C. Kleene. The logic of Doherty provides a flexible framework in defining, ...
    • Toward a realistic semantics of possible worlds for logics of belief 

      Sales Porta, Ton; Alvarado Mentado, Matías (1993-09)
      External research report
      Open Access
      This work sets out the main ideas concerning a semantics of possible worlds for epistemic logics which do not have the problem of logical omniscience and which can be used to model reasoning with limited resources. Within ...
