    • 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 ...
    • 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 (Springer Verlag, 2018)   Contribución a congreso / Biltzarrerako ekarpena
      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; Miguel Turullols, Laura de Upna; Mesiar, Radko; Fernández Fernández, Francisco Javier Upna; Bustince Sola, Humberto Upna (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; 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; Jin, LeSheng; Mesiar, Radko; Vavríková, Lucia; Bustince Sola, Humberto Upna (IEEE, 2019)   Contribución a congreso / Biltzarrerako ekarpena
      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; Pereira Dimuro, Graçaliz Upna; Bedregal, Benjamin; 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 ...
    • Strengthened ordered directional and other generalizations of monotonicity for aggregation functions 

      Sesma Sara, Mikel Upna; Miguel Turullols, Laura de Upna; Lafuente López, Julio Upna; Barrenechea Tartas, Edurne Upna; Mesiar, Radko; Bustince Sola, Humberto Upna (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; 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 ...
