    A malfunction of a wastewater treatment plant is a big social and biological problem. A poorly treated waste water outside the plant could provoke dangerous consequences for human beings as well as the nature itself. The ...
  • LINNEO+: a classification methodology for ill-structured domains 

    Béjar Alonso, Javier; Cortés García, Claudio Ulises; Poch, Manel (1993-04)
    Report de recerca
    Accés obert
    In this work we present a methodology oriented to domains with a weak structure (ill-domains) for, using inductive conceptual learning techniques (descriptive generalization) and classification, discover concepts through ...
  • Supporting decision making in urban wastewater systems using a knowledge-based approach

    The use of knowledge-based systems has been shown to be a suitable approach to support decision making in environmental systems. Capturing and managing the huge quantity of data/information that has to be considered is an ...
  • Using entropy-based local weighting to improve similarity assessment 

    Núñez, Héctor; Sànchez-Marrè, Miquel; Cortés García, Claudio Ulises; Comas, Joaquim; Rodriguez-Roda, Ignasi; Poch, Manel (2002-06)
    Report de recerca
    Accés obert
    This paper enhances and analyses the power of local weighted similarity measures. The paper proposes a new entropy-based local weighting algorithm to be used in similarity assessment to improve the performance of the CBR ...
