Sumari

  • Numerical experimentation and comparison of fuzzy integral 

    Bolaños Carmona, Manuel Jorge; Hernández, L.D.; Salmerón, Antonio (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    Sugeno and Choquet integrals have been widely studied in the literature from a theoretical viewpoint. However, the behavior of these functionals is known in a general way, but not in practical applications and in particular ...
  • Concept lattices associated with L-Fuzzy W-contexts 

    Burusco Juandeaburre, Ana; Fuentes-González, Ramón (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    \begin{abstract} \noindent We generalize in this paper the $L$-Fuzzy concept theory we developed in a previous paper ([1]), using the composition of $L$-Fuzzy relations. This theory models knowledge acquisition ...
  • The fuzzy hyperbolic inequality index on fuzzy random variables in finite populations 

    Corral Blanco, Norberto; Gil Álvarez, María de los Ángeles; López-García, Hortensia (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    This paper presents an approach to the problem of quantifying the in-equality of a finite population with respect to a (social, economical, etc.) fuzzy-valued attribute. For this purpose, the fuzzy hyperbolic inequality ...
  • Representation of fuzzy knowledge bases using Petri nets: operation in the truth space 

    Bugarín Diz, Alberto José; Barro Ameneiro, D. Senén (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    In this paper the execution of Fuzzy Knowledge Bases in the truth space is briefly analyzed. The computational efficiency of the process is significantly increased by means of a parameterized description based on the ...
  • Using fuzzy similiarity relations to revise and update a knwoledge base 

    Rodríguez, Ricardo Óscar; Garcia, Pere; Godo Lacasa, Lluís (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    Similarity-based models were first used by Ruspini to give semantics to fuzzy logic ([7]). In these models, incomplete information is represented by an evidential set, i.e. a set of possible worlds that are compatible ...
  • Neural methods for obtaining fuzzy rules 

    Benítez Sánchez, José Manuel; Blanco Morón, Armando; Delgado Calvo-Flores, Miguel; Requena Ramos, Ignacio (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    In previous papers, we presented an empirical methodology based on Neural Networks for obtaining fuzzy rules which allow a system to be described, using a set of examples with the corresponding inputs and outputs. Now ...
  • A dual approach in fuzzy linear programming 

    Cadenas Figueredo, José Manuel; Jiménez Barrionuevo, Fernando (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    In this paper, we propose a relationship of fuzzy duality. We use the Decomposition Theorem and some properties about Linear Programming with interval coefficients to define this relationship. Thus, a linear programming ...
  • Phrase structure grammars for the expression of vague voncepts in Spanish 

    Sobrino Cerdeiriña, Alejandro; Olivas Varela, José Ángel (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    This paper characterizes grammars generating Spanish sentences of imprecise meaning. The basic grammar generating sentences onforming to the standard paradigm of fuzzy logic (Quantifier + Noun + Verb + Modifier + Adjective) ...
  • Contributions to the symbolic processing of segments in computer vision 

    Cabrera Gámez, Juan; Hernández Tejara, Francisco Mario; Falcón Martel, Antonio; Méndez, J. (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    In this paper a processing methodology is introduced for the segment or intermediate level in the context of knowledge-based computer vision systems. The proposed methodology demonstrates how using simple Fuzzy Logic ...
  • Client/server architecture for fuzzy relational databases 

    Medina Rodríguez, Juan Miguel; Pons Capote, Olga; Vila Miranda, María Amparo; Cubero Talavera, Juan Carlos (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    This paper shows a FRDBMS architecture whose main characteristics are: 1) it is implemented entirely on classical RDBMS just using the resources provided by them, 2) it preserves all the operations and qualities of the ...
  • Automatic synthesis of fuzzy logic controlers 

    Barriga Barrios, Ángel; Sánchez Solano, Santiago; Jiménez, Carlos J.; Galán, D.; López, Diego R. (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    This paper describes a design environment for the hardware realizations of fuzzy controllers which includes a set of CAD tools to ease the description, verification and synthesis of this kind of systems. Special emphasis ...
  • Learning under hardware restrictions in CMOS fuzzy controlers able to extract rules from examples 

    Vidal Verdú, Fernando; Navas González, Rafael; Rodríguez-Vázquez, Ángel (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
    Article
    Accés obert
    Fuzzy controllers are able to incorporate knowledge expressed in if-then rules. These rules are given by experts or skilful operators. Problems arise when there are not experts or/and rules are not easy to find. Authors' ...
