    • Construction of admissible linear orders for interval-valued Atanassov intuitionistic fuzzy sets with an application to decision making 

      Miguel Turullols, Laura de Upna; Bustince Sola, Humberto Upna; Fernández Fernández, Francisco Javier Upna; Induráin Eraso, Esteban Upna; Kolesárová, Anna; Mesiar, Radko (Elsevier, 2015)   Artículo / Artikulua  OpenAccess
      In this work we introduce a method for constructing linear orders between pairs of intervals by using aggregation functions. We adapt this method to the case of interval-valued Atanassov intuitionistic fuzzy sets and we ...
    • 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 historical account of types of fuzzy sets and their relationships 

      Bustince Sola, Humberto Upna; Barrenechea Tartas, Edurne Upna; Pagola Barrio, Miguel Upna; Fernández Fernández, Francisco Javier Upna; Xu, Zeshui; Bedregal, Benjamin; Montero, Javier; Hagras, Hani; Herrera, Francisco; Baets, Bernard de (IEEE, 2016)   Artículo / Artikulua  OpenAccess
      In this work we review the definition and basic properties of the different types of fuzzy sets that have appeared up to now in the literature. We also analyze the relationships between them and enumerate some of the ...
    • Improving the performance of fuzzy rule-based classification systems based on a nonaveraging generalization of CC-integrals named C-F1F2-integrals 

      Lucca, Giancarlo; Pereira Dimuro, Graçaliz Upna; Fernández Fernández, Francisco Javier Upna; Bustince Sola, Humberto Upna; Bedregal, Benjamin; Sanz Delgado, José Antonio (IEEE, 2019)   Artículo / Artikulua
      A key component of fuzzy rule-based classification systems (FRBCS) is the fuzzy reasoning method (FRM) since it infers the class predicted for new examples. A crucial stage in any FRM is the way in which the information ...
    • Interval type-2 fuzzy sets are generalization of interval-valued fuzzy sets: towards a wider view on their relationship 

      Bustince Sola, Humberto Upna; Fernández Fernández, Francisco Javier Upna; Hagras, Hani; Herrera, Francisco; Pagola Barrio, Miguel Upna; Barrenechea Tartas, Edurne Upna (IEEE, 2015)   Artículo / Artikulua  OpenAccess
      In this paper, we will present a wider view on the relationship between interval-valued fuzzy sets and interval type- 2 fuzzy sets where we will show that interval-valued fuzzy sets are a particular case of the interval ...
    • 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, ...
