Summary

  • On a new class of distances between fuzzy numbers 

    Bertoluzza, Carlo; Corral Blanco, Norberto; Salas, Antonia (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
    Article
    Open Access
    In the course of the studies on fuzzy regression analysis, we encountered the problem of introducing a distance between fuzzy numbers, which replaces the classical (x-y)² on the real line. Our proposal is to compute such ...

  • A chunking mechanism in a neural system for the parallel processing of a propositional production rules 

    Burattini, E.; Pasconcino, A.; Tamburrini, G. (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
    Article
    Open Access
    The problem of extracting more compact rules from a rule-based knowledge base is approached by means of a chunking mechanism implemented via a neural system. Taking advantage of the parallel processing potentialities of ...

  • Intuitionistic fuzzy relations (Part II) Effect of Atanassov's operators on the properties of the intuitionistic fuzzy relations 

    Burillo López, Pedro; Bustince Sola, Humberto Nicanor (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
    Article
    Open Access
    In this paper we study the effect of Atanassov's operator on the properties of properties reflexive, symmetric, antisymmetric, perfect antisymmetric and transitive intuitionistic fuzzy relations. We finish the paper analysing ...

  • Remark on intuitionistic fuzzy logic and intuitionistic logic 

    Atanassov, Krassimir T. (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
    Article
    Open Access
    It is shown that the axioms of the intuitionistic logic can be proved as theorems in the frames of the intuitionistic fuzzy logic.
