    • Aggregation functions based on the Choquet integral applied to image resizing 

      Bueno, Jéssica C. S.; Dias, Camila A.; Pereira Dimuro, Graçaliz Upna Orcid; Santos, Helida; Bustince Sola, Humberto Upna Orcid (Atlantis Press, 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The rising volume of data and its high complexity has brought the need of developing increasingly efficient knowledge extraction techniques, which demands efficiency both in computational cost and in accuracy. Most of ...
    • Funções de agregação baseadas em integral de Choquet aplicadas em redimensionalização de imagens 

      Bueno, Jéssica C. S.; Dias, Camila A.; Pereira Dimuro, Graçaliz Upna Orcid; Borges, Eduardo N.; Botelho, Silvia S. C.; Mattos, Viviane L. D. de; Bustince Sola, Humberto Upna Orcid (Universidade Passo Fundo, 2019)   Artículo / Artikulua  OpenAccess
      The increasing data volume, coupled with the high complexity of these data, has generated the need to develop increasingly efficient knowledge extraction techniques, both in computational cost and precision. Most of the ...
    • General overlap functions 

      Miguel Turullols, Laura de Upna Orcid; Gomez, Daniel; Tinguaro, Javier; Montero, Javier; Bustince Sola, Humberto Upna Orcid; Pereira Dimuro, Graçaliz Upna Orcid; Sanz, Jose Antonio (Elsevier, 2019)   Artículo / Artikulua
      As a generalization of bivariate overlap functions, which measure the degree of overlapping (intersection for non-crisp sets) of n different classes, in this paper we introduce the concept of general overlap functions. We ...
    • Learning fuzzy measures for aggregation in fuzzy rule-based models 

      Saleh, Emran; Valls, Aida; Moreno, Antonio Upna; Romero-Aroca, Pedro; Torra, Vicenç; Bustince Sola, Humberto Upna Orcid (Springer Verlag, 2018)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Fuzzy measures are used to express background knowledge of the information sources. In fuzzy rule-based models, the rule confidence gives an important information about the final classes and their relevance. This work ...
    • Local properties of strengthened ordered directional and other forms of monotonicity 

      Sesma Sara, Mikel Upna Orcid; Miguel Turullols, Laura de Upna Orcid; Mesiar, Radko; Fernández Fernández, Francisco Javier Upna Orcid; Bustince Sola, Humberto Upna Orcid (Springer, 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this study we discuss some of the recent generalized forms of monotonicity, introduced in the attempt of relaxing the monotonicity condition of aggregation functions. Specifically, we deal with weak, directional, ordered ...
    • Orness for idempotent aggregation functions 

      Legarreta, Leire; Lizasoain Iriso, María Inmaculada Upna Orcid; Mardones Pérez, Iraide (MDPI, 2017)   Artículo / Artikulua  OpenAccess
      Aggregation functions are mathematical operators that merge given data in order to obtain a global value that preserves the information given by the data as much as possible. In most practical applications, this value is ...
    • OWA operators based on admissible permutations 

      Paternain Dallo, Daniel Upna Orcid; Jin, LeSheng; Mesiar, Radko; Vavríková, Lucia; Bustince Sola, Humberto Upna Orcid (IEEE, 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this work we propose a new OWA operator defined on bounded convex posets of a vector-lattice. In order to overcome the non-existence of a total order, which is necessary to obtain a non-decreasing arrangement of the ...
    • Pre-aggregation functions: construction and an application 

      Lucca, Giancarlo; Sanz Delgado, José Antonio Upna Orcid; Pereira Dimuro, Graçaliz Upna Orcid; Bedregal, Benjamin Upna; Mesiar, Radko; Kolesárová, Anna; Bustince Sola, Humberto Upna Orcid (IEEE, 2015)   Artículo / Artikulua  OpenAccess
      In this work we introduce the notion of preaggregation function. Such a function satisfies the same boundary conditions as an aggregation function, but, instead of requiring monotonicity, only monotonicity along some ...
    • A proposal for tuning the α parameter in CαC-integrals for application in fuzzy rule-based classification systems 

      Lucca, Giancarlo; Sanz Delgado, José Antonio Upna Orcid; Pereira Dimuro, Graçaliz Upna Orcid; Bedregal, Benjamin Upna; Bustince Sola, Humberto Upna Orcid (Springer, 2020)   Artículo / Artikulua  OpenAccess
      In this paper, we consider the concept of extended Choquet integral generalized by a copula, called CC-integral. In particular, we adopt a CC-integral that uses a copula defined by a parameter α, which behavior was tested ...
    • Strengthened ordered directional and other generalizations of monotonicity for aggregation functions 

      Sesma Sara, Mikel Upna Orcid; Miguel Turullols, Laura de Upna Orcid; Lafuente López, Julio Upna Orcid; Barrenechea Tartas, Edurne Upna Orcid; Mesiar, Radko; Bustince Sola, Humberto Upna Orcid (Springer, 2018)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      A tendency in the theory of aggregation functions is the generalization of the monotonicity condition. In this work, we examine the latest developments in terms of different generalizations. In particular, we discuss ...
    • Unbalanced interval-valued OWA operators 

      Miguel Turullols, Laura de Upna Orcid; Bustince Sola, Humberto Upna Orcid; Barrenechea Tartas, Edurne Upna Orcid; Pagola Barrio, Miguel Upna Orcid; Fernández Fernández, Francisco Javier Upna Orcid (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 ...
