    • Análisis de titulaciones universitarias basadas en competencias mediante una técnica de clustering evolutiva multiobjetivo 

      García Piquer, Álvaro; Fornells Herrera, Albert; Golobardes, Elisabet; Orriols Puig, Albert; Cugota Florejachs, Laia (2010-09)
      Las competencias son la piedra angular en base a la cual giran los modelos educativos en la actualidad y, por ello, el correcto estudio de su relación entre las asignaturas y la manera como son evaluadas ...

    • Applying Distance Metric Learning in a Collaborative Melanoma Diagnosis System with Case-Based Reasoning 

      Nicolàs Sans, Rubén; Vernet Bellet, David; Golobardes, Elisabet; Fornells Herrera, Albert; Torre Frade, Fernando de la; Puig, Susana (Proceedings of the 14th Workshop on Case-based reasoning at the 29th SGAI International Conference on Innovative Techniques and Applications of Artificial Intelligence, 2011-12)
      Current social habits in solar exposure have increased the appearance of melanoma cancer in the last few years. The highest mortality rates in dermatological cancers are caused for this illness. In spite ...

    • BASTIAN: incorporating the Rough Sets theory into a Case-Bases Classifier System 

      Salamó Llorente, Maria; Golobardes, Elisabet (2000-10)
      This paper proposes how to incorporate the Rough Sets theory as a weighting method into a Case-Based Classifier System. This hybrid system has been implemented into the plat­form called BASTIAN ( ...

    • Classifying Microcalcifications in Digital Mammograms using Machine Learning techniques 

      Golobardes, Elisabet; Martí, Joan; Español, Josep; Salamó Llorente, Maria; Freixenet, Jordi; Llorà Fàbrega, Xavier; Maroto, Albert; Bernadó Mansilla, Ester (2001-10)
      This paper presents a Computer Aided Diag­nosis (CAD) of breast cancer from mammograms. The first part involves severa! image processing techniques, which extract a set of features from the microcalcifications ...

    • Comparison of Strategies Based on Evolutionary Computation for the Design of Similarity Functions 

      Fornells Herrera, Albert; Camps Dausà, Joan; Golobardes, Elisabet; Garrell i Guiu, Josep Maria (Proceedings of the 8th International Conference of the ACIA, 2005-10)
      One of the main keys in case-based reasoning system is the retrievalphase, where the most similar cases are retrieved by means of a similarity function.According to the problem, the ...

    • ¿Cómo predecir la evolución del alumno? 

      Vernet Bellet, David; Salamó Llorente, Maria; Vallespí, Carles; Camps Dausà, Joan; Golobardes, Elisabet (Actas de las VII Jornadas de Enseñanza universitaria de la Informática, 2001-07)
      Un aspecto muy importante en la enseñanza acualquier nivel es poder predecir a tiempo si unalumno conseguirá superar una asignatura. De estamanera, si se detecta a tiempo una desviación enel aprendizaje ...

    • Decision Support System for the Breast Cancer Diagnosis by a Meta-learning Approach based on Grammar Evolution 

      Fornells Herrera, Albert; Golobardes, Elisabet; Bernado Mansilla, Ester; Martí Bonmatí, Joan (2006-05)
      The incidence of breast cancer varies greatly among countries, but statistics show that every year 720,000 new cases will be diagnosed world-wide. However, a low percentage of women who suffer it can ...

    • Generació de funcions de similitud mitjançant la Programació Genetica pel Raonament Basat en Casos 

      Golobardes, Elisabet; Nieto, Mireya; Camps Dausà, Joan; Calzada, Gemma; Martí, Joan; Vernet Bellet, David; Salamó Llorente, Maria (2001-10)
      El raonament basat en casos recupera casos utilit­zant una funció de similitud. La funció de simi­litud permet extraure els casos més similars de la memoria de casos al nou cas que volem resoldre. Per ...

    • Genetic Classifier System as a heuristic weighting method for a Case-Based Classifier System 

      Golobardes, Elisabet; Llorà Fàbrega, Xavier; Garrell i Guiu, Josep Maria; Vernet Bellet, David; Bacardit Peñarroya, Jaume (2000-10)
      This paper proposes how to use a Genetic Classi­fier System as a heuristic weighting method for a Case-Based Classifier System. The preliminary re­sults are performed into a specific domain: the pre­diction ...

    • Hybrid Deletion Policies for Case Base Maintenance 

      Salamó Llorente, Maria; Golobardes, Elisabet (Proceeding of the 16th International Florida Artificial Intelligence Research Society Conference, 2003-05)
      Case memory maintenance in a Case-Based Reasoning sys-tem is important for two main reasons: (1) to control the casememory size; (2) to reduce irrelevant and redundant instancesthat may produce ...
