• Affine construction methodology of aggregation functions 

      Roldán López de Hierro, Antonio Francisco; Roldán, Concepción; Bustince Sola, Humberto Upna Orcid; Fernández Fernández, Francisco Javier Upna Orcid; Rodríguez Martínez, Iosu Upna Orcid; Fardoun, Habib; Lafuente López, Julio Upna Orcid (Elsevier, 2020)   Artículo / Artikulua  OpenAccess
      Aggregation functions have attracted much attention in recent times because of its potential use in many areas such us data fusion and decision making. In practice, most of the aggregation functions that scientists use in ...
    • Curve-based monotonicity: a generalization of directional monotonicity 

      Roldán López de Hierro, Antonio Francisco; Sesma Sara, Mikel Upna Orcid; Špirková, Jana; Lafuente López, Julio Upna Orcid; Pradera, Ana; Mesiar, Radko; Bustince Sola, Humberto Upna Orcid (Taylor & Francis, 2019)   Artículo / Artikulua  OpenAccess
      In this work we propose a generalization of the notion of directional monotonicity. Instead of considering increasingness or decreasingness along rays, we allow more general paths defined by curves in the n-dimensional ...
    • Degree of totalness: how to choose the best admissible permutation for vector fuzzy integration 

      Ferrero Jaurrieta, Mikel; Horanská, Lubomíra; Lafuente López, Julio Upna Orcid; Mesiar, Radko; Pereira Dimuro, Graçaliz Upna Orcid; Takáč, Zdenko; Gómez Fernández, Marisol Upna Orcid; Fernández Fernández, Francisco Javier Upna Orcid; Bustince Sola, Humberto Upna Orcid (Elsevier, 2023)   Artículo / Artikulua
      The use of aggregation operators that require ordering of the data brings a problem when the structures to be aggregated are multi-valued, since there may be several admissible orders. To addressing this problem, the concept ...
    • Interval subsethood measures with respect to uncertainty for the interval-valued fuzzy setting 

      Pekala, Barbara; Bentkowska, Urszula; Sesma Sara, Mikel Upna Orcid; Fernández Fernández, Francisco Javier Upna Orcid; Lafuente López, Julio Upna Orcid; Altalhi, A. H.; Knap, Maksymilian; Bustince Sola, Humberto Upna Orcid; Pintor Borobia, Jesús María Upna Orcid (Atlantis Press, 2020)   Artículo / Artikulua  OpenAccess
      In this paper, the problem of measuring the degree of subsethood in the interval-valued fuzzy setting is addressed. Taking into account the widths of the intervals, two types of interval subsethood measures are proposed. ...
    • A new family of aggregation functions for intervals 

      Díaz-Vázquez, Susana; Torres-Manzanera, Emilio; Rico, Noelia; Mesiar, Radko; Rodríguez Martínez, Iosu Upna Orcid; Lafuente López, Julio Upna Orcid; Díaz, Irene; Montes, Susana; Bustince Sola, Humberto Upna Orcid (Springer, 2024)   Artículo / Artikulua  OpenAccess
      Aggregation operators are unvaluable tools when different pieces of information have to be taken into account with respect to the same object. They allow to obtain a unique outcome when different evaluations are available ...
    • Ordered directional monotonicity in the construction of edge detectors 

      Marco Detchart, Cedric Upna Orcid; Bustince Sola, Humberto Upna Orcid; Fernández Fernández, Francisco Javier Upna Orcid; Mesiar, Radko; Lafuente López, Julio Upna Orcid; Barrenechea Tartas, Edurne Upna Orcid; Pintor Borobia, Jesús María Upna Orcid (Elsevier, 2021)   Artículo / Artikulua  OpenAccess
      In this paper we provide a specific construction method of ordered directionally monotone functions. We show that the functions obtained with this construction method can be used to build edge detectors for grayscale images. ...
    • Replacing pooling functions in convolutional neural networks by linear combinations of increasing functions 

      Rodríguez Martínez, Iosu Upna Orcid; Lafuente López, Julio Upna Orcid; Santiago, Regivan; Pereira Dimuro, Graçaliz Upna Orcid; Herrera, Francisco; Bustince Sola, Humberto Upna Orcid (Elsevier, 2022)   Artículo / Artikulua  OpenAccess
      Traditionally, Convolutional Neural Networks make use of the maximum or arithmetic mean in order to reduce the features extracted by convolutional layers in a downsampling process known as pooling. However, there is no ...
    • Strengthened ordered directionally monotone functions. Links between the different notions of monotonicity 

      Sesma Sara, Mikel Upna Orcid; Lafuente López, Julio Upna Orcid; Roldán López de Hierro, Antonio Francisco; Mesiar, Radko; Bustince Sola, Humberto Upna Orcid (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      In this work, we propose a new notion of monotonicity: strengthened ordered directional monotonicity. This generalization of monotonicity is based on directional monotonicity and ordered directional monotonicity, two recent ...
