Affine construction methodology of aggregation functions
Roldán López de Hierro, Antonio F.; Roldán, Concepción; Bustince Sola, Humberto
; Fernández Fernández, Francisco Javier ; Rodríguez Martínez, Iosu ; Fardoun, Habib; Lafuente López, Julio (Elsevier, 2020)
Artículo / Artikulua
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 ... -
Consensus image method for unknown noise removal
González Jaime, Luis; Kerre, Etienne E.; Nachtegael, Mike; Bustince Sola, Humberto (Elsevier, 2014)
Artículo / Artikulua 
Noise removal has been, and it is nowadays, an important task in computer vision. Usually, it is a previous task preceding other tasks, as segmentation or reconstruction. However, for most existing denoising algorithms the ... -
d-Choquet integrals: Choquet integrals based on dissimilarities
Bustince Sola, Humberto; Mesiar, Radko; Fernández Fernández, Francisco Javier ; Galar Idoate, Mikel ; Paternain Dallo, Daniel ; Altalhi, A. H.; Pereira Dimuro, Graçaliz ; Bedregal, Benjamin ; 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 ... -
Description and properties of curve-based monotone functions
Sesma Sara, Mikel; Miguel Turullols, Laura de ; Roldán López de Hierro, Antonio F.; Špirková, Jana; Mesiar, Radko; Bustince Sola, Humberto (Springer, 2019)
Contribución a congreso / Biltzarrerako ekarpena
Curve-based monotonicity is one of the lately introduced relaxations of monotonicity. As directional monotonicity regards monotonicity along fixed rays, which are given by real vectors, curve-based monotonicity studies the ... -
Directions of directional, ordered directional and strengthened ordered directional increasingness of linear and ordered linear fusion operators
Sesma Sara, Mikel; Marco Detchart, Cedric ; Lafuente López, Julio ; Roldán, Antonio; Mesiar, Radko; Bustince Sola, Humberto (IEEE, 2019)
Contribución a congreso / Biltzarrerako ekarpena
In this work we discuss the forms of monotonicity that have been recently introduced to relax the monotonicity condition in the definition of aggregation functions. We focus on directional, ordered directional and strengthened ... -
Interval subsethood measures with respect to uncertainty for the interval-valued fuzzy setting
Pekala, Barbara; Bentkowska, Urszula; Sesma Sara, Mikel; Fernández Fernández, Francisco Javier ; Lafuente López, Julio ; Altalhi, A. H.; Knap, Maksymilian; Bustince Sola, Humberto ; Pintor Borobia, Jesús María (Atlantis Press, 2020)
Artículo / Artikulua
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. ... -
Mixture functions and their monotonicity
Špirková, Jana; Beliakov, Gleb; Bustince Sola, Humberto ; Fernández Fernández, Francisco Javier (Elsevier, 2019)
Artículo / Artikulua
We consider mixture functions, which are a type of weighted averages for which the corresponding weights are calculated by means of appropriate continuous functions of their inputs. In general, these mixture function need ... -
Moderate deviation and restricted equivalence functions for measuring similarity between data
Altalhi, A. H.; Forcén, J. I.; Pagola Barrio, Miguel; Barrenechea Tartas, Edurne ; Bustince Sola, Humberto ; Takáč, Zdenko (Elsevier, 2019)
Artículo / Artikulua
In this work we study the relation between moderate deviation functions, restricted dissimilarity functions and restricted equivalence functions. We use moderate deviation functions in order to measure the similarity or ... -
Nested formulation paradigms for induced ordered weighted averaging aggregation for decision‐making and evaluation
Zhu, Chen; Jin, LeSheng; Mesiar, Radko; Yager, Ronald R.; Paternain Dallo, Daniel; Bustince Sola, Humberto (Wiley, 2019)
Artículo / Artikulua
Existing extensions to Yager's ordered weighted aver-aging (OWA) operators enlarge the application rangeand to encompass more principles and properties relatedto OWA aggregation. However, these extensions do notprovide a ... -
Some properties of implications via aggregation functions and overlap functions
Zapata, Hugo; Bustince Sola, Humberto; Miguel Turullols, Laura de ; Guerra, Carlos (Taylor & Francis, 2014)
Artículo / Artikulua
In this work, using the identification between implication operators and aggregation functions, we study the implication operators that are recovered from overlap functions. In particular, we focus in which properties ... -
T-overlap functions: a generalization of bivariate overlap functions by t-norms
Zapata, Hugo; Pereira Dimuro, Graçaliz; Fernández Fernández, Francisco Javier ; Bustince Sola, Humberto (Springer, 2018)
Contribución a congreso / Biltzarrerako ekarpena
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 ... -
Weak and directional monotonicity of functions on Riesz spaces to fuse uncertain data
Sesma Sara, Mikel; Mesiar, Radko; Bustince Sola, Humberto (Elsevier B.V., 2019)
Artículo / Artikulua
In the theory of aggregation, there is a trend towards the relaxation of the axiom of monotonicity and also towards the extension of the definition to other domains besides real numbers. In this work, we join both approaches ...
