  • (┬,┴,N) Fuzzy logic 

    Xu, Y.; Liu, J.; Ruan, Da (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
    Article
    Accés obert
    To investigate more reasonable fuzzy reasoning model in expert systems as well as more effective logical circuit in fuzzy control, a $(\top, \bot, N)$ fuzzy logic is proposed in this paper by using $\top$-norm, $\bot$-norm ...

  • Averaging Premises 

    Trillas i Gay, Enric; Castiñeira Holgado, Elena Esther; Cubillo Villanueva, Susana (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
    Article
    Accés obert
    This paper deals with the sets of strict conjectures and consequences of a given collection $P$ of premises. The set of Averaging Functions is introduced on lattices and some properties of these functions are shown. ...

  • Marginalization like a projection 

    Verdegay López, Juan Francisco; Moral Callejón, Serafín (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
    Article
    Accés obert
    This paper studies the problem of marginalizing convex polytopes of probabilities represented by a set of constraints. This marginalization is obtained as a special case of projection on a specific subspace. An algorithm ...

  • Rule-based fuzzy object similarity 

    Bunke, Horst; Fàbregas, Xavier; Kandel, Abraham (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
    Article
    Accés obert
    A new similarity measure for objects that are represented by feature vectors of fixed dimension is introduced. It can simultaneously deal with numeric and symbolic features. Also, it can tolerate missing feature values. ...

  • Fuzzy set theory for cumulative trauma prediction 

    Fonseca, Daniel J.; Merritt, Thomas W.; Moynihan, Gary P. (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
    Article
    Accés obert
    A widely used fuzzy reasoning algorithm was modified and implemented via an expert system to assess the potential risk of employee repetitive strain injury in the workplace. This fuzzy relational model, known as the ...

  • A formal analisys of the computational dynamics in GIGANTEC 

    Badr, Amr (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
    Article
    Accés obert
    An evolutionary algorithm formalism has been forwarded in a previous research, and implemented in the system GIGANTEC: Genetic Induction for General Analytical Non-numeric Task Evolution Compiler [Bad98][Bad99]. A dynamical ...

  • A multi-agent system based on fuzzy logic applied to RoboCup's enviroment 

    Aguirre Molina, Eugenio; Gámez, Juan Carlos; González Muñoz, Antonio (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
    Article
    Accés obert
    Artificial Intelligent has been applied successfully to many and varied domains. In particular, the recent steps forward which are been producing in the development of dynamic, collaborative, real time and adversarial ...

  • A multicriteria genetic tuning for fuzzy logic controllers 

    Alcalá Fernández, Rafael; Casillas Barranquero, Jorge; Castro Peña, Juan Luis; González Muñoz, Antonio; Herrera Triguero, Francisco (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
    Article
    Accés obert
    This paper presents the use of genetic algorithms to develop smartly tuned fuzzy logic controllers in multicriteria complex problems. This tuning approach has some specific restrictions that make it very particular and ...
