• Enhancing multi-class classification in FARC-HD fuzzy classifier: on the synergy between n-dimensional overlap functions and decomposition strategies 

      Elkano Ilintxeta, Mikel Upna; Galar Idoate, Mikel Upna; Sanz Delgado, José Antonio Upna; Fernández, Alberto; Barrenechea Tartas, Edurne Upna; Herrera, Francisco; Bustince Sola, Humberto Upna (IEEE, 2014)   Artículo / Artikulua  OpenAccess
      There are many real-world classification problems involving multiple classes, e.g., in bioinformatics, computer vision or medicine. These problems are generally more difficult than their binary counterparts. In this scenario, ...
    • Extensions of fuzzy sets in image processing: an overview 

      Pagola Barrio, Miguel Upna; Barrenechea Tartas, Edurne Upna; Bustince Sola, Humberto Upna; Fernández Fernández, Francisco Javier Upna; Galar Idoate, Mikel Upna; Jurío Munárriz, Aránzazu Upna; López Molina, Carlos Upna; Paternain Dallo, Daniel Upna; Sanz Delgado, José Antonio Upna; Couto, P.; Melo Pinto, P. (EUSFLAT, 2011)   Artículo / Artikulua  OpenAccess
      This work presents a valuable review for the interested reader of the recent Works using extensions of fuzzy sets in image processing. The chapter is divided as follows: first we recall the basics of the extensions of fuzzy ...
    • A survey of fingerprint classification Part I: taxonomies on feature extraction methods and learning models 

      Galar Idoate, Mikel Upna; Derrac, Joaquín; Peralta, Daniel; Triguero, Isaac; Paternain Dallo, Daniel Upna; López Molina, Carlos Upna; García, Salvador; Benítez, José Manuel; Pagola Barrio, Miguel Upna; Barrenechea Tartas, Edurne Upna; Bustince Sola, Humberto Upna; Herrera, Francisco (Elsevier, 2015)   Artículo / Artikulua  OpenAccess
      This paper reviews the fingerprint classification literature looking at the problem from a double perspective. We first deal with feature extraction methods, including the different models considered for singular point ...
    • A survey of fingerprint classification Part II: experimental analysis and ensemble proposal 

      Galar Idoate, Mikel Upna; Derrac, Joaquín; Peralta, Daniel; Triguero, Isaac; Paternain Dallo, Daniel Upna; López Molina, Carlos Upna; García, Salvador; Benítez, José Manuel; Pagola Barrio, Miguel Upna; Barrenechea Tartas, Edurne Upna; Bustince Sola, Humberto Upna; Herrera, Francisco (Elsevier, 2015)   Artículo / Artikulua  OpenAccess
      In the first part of this paper we reviewed the fingerprint classification literature from two different perspectives: the feature extraction and the classifier learning. Aiming at answering the question of which among the ...
    • A survey on fingerprint minutiae-based local matching for verification and identification: taxonomy and experimental evaluation 

      Peralta, Daniel; Galar Idoate, Mikel Upna; Triguero, Isaac; Paternain Dallo, Daniel Upna; García, Salvador; Barrenechea Tartas, Edurne Upna; Benítez, José Manuel; Bustince Sola, Humberto Upna; Herrera, Francisco (Elsevier, 2015)   Artículo / Artikulua  OpenAccess
      Fingerprint recognition has found a reliable application for verification or identification of people in biometrics. Globally, fingerprints can be viewed as valuable traits due to several perceptions observed by the experts; ...
    • Unbalanced interval-valued OWA operators 

      Miguel Turullols, Laura de Upna; Bustince Sola, Humberto Upna; Barrenechea Tartas, Edurne Upna; Pagola Barrio, Miguel Upna; Fernández Fernández, Francisco Javier Upna (Springer Berlin Heidelberg, 2016)   Artículo / Artikulua  OpenAccess
      In this work, we introduce a new class of functions defned on the interval-valued setting. These functions extend classical OWA operators but allow for diferent weighting vectors to handle the lower bounds and the ...
    • Using the Choquet integral in the fuzzy reasoning method of fuzzy rule-based classification systems 

      Barrenechea Tartas, Edurne Upna; Bustince Sola, Humberto Upna; Fernández Fernández, Francisco Javier Upna; Paternain Dallo, Daniel Upna; Sanz Delgado, José Antonio Upna (MDPI, 2013)   Artículo / Artikulua  OpenAccess
      In this paper we present a new fuzzy reasoning method in which the Choquet integral is used as aggregation function. In this manner, we can take into account the interaction among the rules of the system. For this reason, ...
