    • d-Choquet integrals: Choquet integrals based on dissimilarities 

      Bustince Sola, Humberto Upna; Mesiar, Radko; Fernández Fernández, Francisco Javier Upna; Galar Idoate, Mikel Upna; Paternain Dallo, Daniel Upna; Altalhi, A. H.; Pereira Dimuro, Graçaliz Upna; Bedregal, Benjamin Upna; Takáč, Zdenko (Elsevier, 2020)   Artículo / Artikulua
      The paper introduces a new class of functions from [0,1]n to [0,n] called d-Choquet integrals. These functions are a generalization of the 'standard' Choquet integral obtained by replacing the difference in the definition ...
    • Funções de agregação baseadas em integral de Choquet aplicadas em redimensionalização de imagens 

      Bueno, Jéssica C. S.; Dias, Camila A.; Pereira Dimuro, Graçaliz Upna; Borges, Eduardo N.; Botelho, Silvia S. C.; Mattos, Viviane L. D. de; Bustince Sola, Humberto Upna (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; Gomez, Daniel; Tinguaro, Javier; Montero, Javier; Bustince Sola, Humberto Upna; Pereira Dimuro, Graçaliz Upna; 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 ...
    • 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 Upna; Sanz Delgado, José Antonio Upna (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      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 ...
    • The law of O-conditionality for fuzzy implications constructed from overlap and grouping functions 

      Pereira Dimuro, Graçaliz Upna; Bedregal, Benjamin Upna; Fernández Fernández, Francisco Javier Upna; Sesma Sara, Mikel Upna; Pintor Borobia, Jesús María Upna; Bustince Sola, Humberto Upna (Elsevier, 2019)   Artículo / Artikulua
      Overlap and grouping functions are special kinds of non necessarily associative aggregation operators proposed for many applications, mainly when the associativity property is not strongly required. The classes of overlap ...
    • Multimodal fuzzy fusion for enhancing the motor-imagery-based brain computer interface 

      Ko, Li-Wei; Lu, Yi-Chen; Bustince Sola, Humberto Upna; Chang, Yu-Cheng; Chang, Yang; Fernández Fernández, Francisco Javier Upna; Wang, Yu-Kai; Sanz Delgado, José Antonio Upna; Pereira Dimuro, Graçaliz Upna; Lin, Chin-Teng (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      Brain–computer interface technologies, such as steady-state visually evoked potential, P300, and motor imagery are methods of communication between the human brain and the external devices. Motor imagery–based brain–computer ...
    • On some classes of directionally monotone functions 

      Bustince Sola, Humberto Upna; Mesiar, Radko; Kolesárová, Anna; Pereira Dimuro, Graçaliz Upna; Fernández Fernández, Francisco Javier Upna; Díaz, Irene; Montes, S. (Elsevier, 2020)   Artículo / Artikulua
      In this work we consider some classes of functions with relaxed monotonicity conditions generalizing some other given classes of fusion functions. In particular, directionally increasing aggregation functions (called also ...
    • Pre-aggregation functions: construction and an application 

      Lucca, Giancarlo; Sanz Delgado, José Antonio Upna; Pereira Dimuro, Graçaliz Upna; Bedregal, Benjamin Upna; Mesiar, Radko; Kolesárová, Anna; Bustince Sola, Humberto Upna (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 ...
    • T-overlap functions: a generalization of bivariate overlap functions by t-norms 

      Zapata, Hugo; Pereira Dimuro, Graçaliz Upna; Fernández Fernández, Francisco Javier Upna; Bustince Sola, Humberto Upna (Springer, 2018)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      This paper introduces a generalization of overlap functions by extending one of the boundary conditions of its definition. More specifically, instead of requiring that 'the considered function is equal to zero if and only ...
