    Article
    Accés obert
    In this paper, an architecture of fuzzy neural networks is proposed to find a real root of a dual fuzzy polynomial (if exists) by introducing a learning algorithm. We proposed a learning algorithm from the cost function ...
  • Fuzzy numbers and equality relations 

    Jacas Moral, Juan; Recasens Ferrés, Jorge (IEEE pub., 1993)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A general approach to the concept of fuzzy number associated to a generalized equality on the real line is given. As a result, the use of triangular and trapezoidal fuzzy numbers, among other types, is justified and a ...
