    • A Soft computing techniques study in wastewater treatment plants 

      Belanche Muñoz, Luis Antonio; Valdés Ramos, Julio José; Comas, Joaquim; Rodriguez-Roda, Ignasi; Poch, Manel (1999-06)
      Report de recerca
      Accés obert
      The correct control and prediction of Wastewater Treatment Plants poses an important goal: to avoid breaking the environmental balance by always keeping the system in stable operating conditions. In this respect, it is ...
    • An analysis of MYCIN-like expert systems 

      Hajek, Petr; Valdés Ramos, Julio José (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1994)
      Article
      Accés obert
      The paper is a review of our theoretical analysis of uncertainty processing in a broad class of truth-functional expert systems similar to MYCIN and PROSPECTOR, main attention being paid to parallel combination of rules. ...
    • Characterizing fractal features for texture description in digital images: an experimental study 

      Molina, Luis; Valdés Ramos, Julio José (2001-03)
      Report de recerca
      Accés obert
      Texture-based recognition for image segmentation and classification is very important in many domains and different numerical features coming from a variety of approaches have been proposed. Texture segmentation using ...
    • Fuzzy heterogeneous heurons for imprecise classification problems 

      Valdés Ramos, Julio José; Belanche Muñoz, Luis Antonio; Alquézar Mancho, René (1998-06)
      Report de recerca
      Accés obert
      In the classical neuron model, inputs are continuous real-valued quantities. However, in many important domains from the real world, objects are described by a mixture of continuous and discrete variables, usually containing ...
    • Fuzzy heterogeneous neural networks for signal forecasting 

      Belanche Muñoz, Luis Antonio; Valdés Ramos, Julio José; Alquézar Mancho, René (Springer, 1998)
      Text en actes de congrés
      Accés obert
      Fuzzy heterogeneous neural networks are recently introduced models based on neurons accepting heterogeneous inputs (i.e. mixtures of numerical and non-numerical information possibly with missing data) with either crisp or ...
    • Fuzzy heterogeneous neurons for imprecise classification problems 

      Valdés Ramos, Julio José; Belanche Muñoz, Luis Antonio; Alquézar Mancho, René (Wiley, 2000-02)
      Article
      Accés obert
      In the classical neuron model, inputs are continuous real-valued quantities. However, in many important domains from the real world, objects are described by a mixture of continuous and discrete variables, usually containing ...
    • Fuzzy inputs and missing data in similarity-based heterogeneous neural networks 

      Belanche Muñoz, Luis Antonio; Valdés Ramos, Julio José (1998-12)
      Report de recerca
      Accés obert
      Fuzzy heterogeneous networks are recently introduced feed-forward neural network models composed of neurons of a general class whose inputs and weights are mixtures of continuous variables (crisp and/or fuzzy) with ...

    • The VEX-93 environment as a hybrid tool for developing knowledge systems with different problem solving techniques 

      Valdés Ramos, Julio José; Hita Rensoli, Ramon María de; Peón Valdés, Katia; Hernández, Dania; García Martínez, Ada; Paredes, Raul; García, Yazna; Rodríguez, Alfredo (1997-02)
      Report de recerca
      Accés obert
      The paper describes VEX-93 as a hybrid environment for developing knowledge-based and problem solver systems. It integrates methods and techniques from artificial intelligence, image and signal processing and data ...
    • Towards a model of input-output behaviour of wastewater treatment plants using soft computing techniques 

      Belanche Muñoz, Luis Antonio; Valdés Ramos, Julio José; Comas Matas, Joaquim; Rodriguez Roda, Ignasi; Poch Espallargas, Manel (Elsevier, 1999-03)
      Article
      Accés obert
      Wastewater Treatment Plants (WWTPs) control and prediction under a wide range of operating conditions is an important goal in order to avoid breaking of environmental balance, keeping the system in stable operating conditions ...
