  • Perfil profesional del ingeniero informático: diagnóstico basado en competencias 

    Martínez Ruíz, Alba; Aluja Banet, Tomàs; Sánchez Carracedo, Fermín (2009-06-19T11:14:31Z)
    Conference report
    Open Access
    Las universidades deben formar los ingenieros que la sociedad necesita. Los planes de Estudios del EEES deben ser diseñados, por tanto, a partir de las competencias profesionales requeridas por la sociedad. Cada escuela, ...
  • PRESISTANT : data pre-processing assistant 

    Bilalli, Besim; Abelló Gamazo, Alberto; Aluja Banet, Tomàs; Munir, Rana Faisal; Wrembel, Robert (Springer, 2019)
    Conference lecture
    Open Access
    A concrete classification algorithm may perform differently on datasets with different characteristics, e.g., it might perform better on a dataset with continuous attributes rather than with categorical attributes, or the ...
  • PRESISTANT: Learning based assistant for data pre-processing 

    Bilalli, Besim; Abelló Gamazo, Alberto; Aluja Banet, Tomàs; Wrembel, Robert (Elsevier, 2019-09)
    Article
    Restricted access - publisher's policy
    Data pre-processing is one of the most time consuming and relevant steps in a data analysis process (e.g., classification task). A given data pre-processing operator can have positive, negative, or zero impact on the final ...
  • The Longitudinal nature of patent value and technological usefulness exploring PLS structural equation models 

    Martínez Ruiz, Alba; Aluja Banet, Tomàs (2010-10)
    External research report
    Open Access
    The purpose of this paper is to investigate the evolution of patent value and technological usefulness over time using longitudinal structural equation models. The variables are modeled as endogenous unobservable variables ...
  • The Pathmox approach for PLS path modeling: discovering which constructs differentiate segments 

    Lamberti, Giuseppe; Aluja Banet, Tomàs; Sanchez Trujillo, Gaston (2017-11)
    Article
    Open Access
    The problem of heterogeneity represents a very important issue in the decision-making process. Furthermore, it has become common practice in the context of marketing research to assume that different population parameters ...
  • The Pathmox approach for PLS path modeling segmentation 

    Lamberti, Giuseppe; Aluja Banet, Tomàs; Sanchez, Gaston (2016-08)
    Article
    Open Access
    Modeling has often failed to meet expectations, mostly because of the difficulty of comprehending relationships within phenomena and expressing them in mathematical models. Reality is frequently too complex to be reflected ...
  • Towards intelligent data analysis : the metadata challenge 

    Bilalli, Besim; Abelló Gamazo, Alberto; Aluja Banet, Tomàs; Wrembel, Robert (2016)
    Conference lecture
    Restricted access - publisher's policy
    Once analyzed correctly, data can yield substantial benefits. The process of analyzing the data and transforming it into knowledge is known as Knowledge Discovery in Databases (KDD). The plethora and subtleties of algorithms ...
  • Un dispositivo gráfico Biplot para modelar relaciones entre dos conjuntos de variables 

    Vásquez, Maura; Ramírez, Guillermo; Camardiel, Alberto; Aluja Banet, Tomàs (2008-09-10)
    Article
    Restricted access - publisher's policy
    En la regresión multivariante se analizan relaciones entre un conjunto de indicadores de un determinado fenómeno (variables y’s) y otro de variables explicativas (variables x’s). Previo a la modelación resulta útil contar ...
