Admissible OWA operators for fuzzy numbers

García-Zamora, Diego; Cruz, Anderson; Neres, Fernando; Santiago, Regivan; Roldán López de Hierro, Antonio Francisco; Paiva, Rui; Dimuro, Graçaliz P.; Martínez López, Luis; Bedregal, Benjamin

; Bustince Sola, Humberto

(Elsevier, 2024) Artículo / Artikulua

Ordered Weighted Averaging (OWA) operators are some of the most widely used aggregation functions in classic literature, but their application to fuzzy numbers has been limited due to the complexity of defining a total ...

Curve-based monotonicity: a generalization of directional monotonicity

Roldán López de Hierro, Antonio Francisco; Sesma Sara, Mikel

; Špirková, Jana; Lafuente López, Julio

; Pradera, Ana; Mesiar, Radko; Bustince Sola, Humberto

(Taylor & Francis, 2019) Artículo / Artikulua

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 ...

Description and properties of curve-based monotone functions

Sesma Sara, Mikel

; Miguel Turullols, Laura de

; Roldán López de Hierro, Antonio Francisco; 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 López de Hierro, Antonio Francisco; 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 ...

Extension of restricted equivalence functions and similarity measures for type-2 fuzzy sets

Miguel Turullols, Laura de

; Santiago, Regivan; Wagner, Christian; Garibaldi, Jonathan M.; Takáč, Zdenko; Roldán López de Hierro, Antonio Francisco; Bustince Sola, Humberto

(IEEE, 2021) Artículo / Artikulua

In this work we generalize the notion of restricted equivalence function for type-2 fuzzy sets, leading to the notion of extended restricted equivalence functions. We also study how under suitable conditions, these new ...

A fuzzy methodology for approaching fuzzy sets of the real line by fuzzy numbers

Roldán López de Hierro, Antonio Francisco; Tíscar, Miguel Ángel; Roldán, Concepción; Bustince Sola, Humberto

(Elsevier, 2021) Artículo / Artikulua

In this paper we introduce a novel methodology to face the problem of finding, for every fuzzy set of the real line, a fuzzy number which can be considered as an approximation of the first one in some reasonable sense. ...

On the notion of fuzzy dispersion measure and its application to triangular fuzzy numbers

Roldán López de Hierro, Antonio Francisco; Bustince Sola, Humberto

; Rueda, María del Mar; Roldán, Concepción; Miguel Turullols, Laura de

; Guerra, Carlos

(Elsevier, 2023) Artículo / Artikulua

In this paper, based on the analysis of the most widely used dispersion measure in the real context (namely, the variance), we introduce the notion of fuzzy dispersion measure associated to a finite set of data given by ...

Quantifying external information in social network analysis: an application to comparative mythology

Fumanal Idocin, Javier

; Cordón García, Óscar; Pereira Dimuro, Graçaliz

; Roldán López de Hierro, Antonio Francisco; Bustince Sola, Humberto

(IEEE, 2023) Artículo / Artikulua

Social network analysis is a popular tool to understand the relationships between interacting agents by studying the structural properties of their connections. However, this kind of analysis can miss some of the domain-specific ...

Strengthened ordered directionally monotone functions. Links between the different notions of monotonicity

Sesma Sara, Mikel

; Lafuente López, Julio

; Roldán López de Hierro, Antonio Francisco; Mesiar, Radko; Bustince Sola, Humberto

(Elsevier, 2019) Artículo / Artikulua

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 ...

Type-(2, k) overlap indices

Roldán López de Hierro, Antonio Francisco; Roldán, Concepción; Tíscar, Miguel Ángel; Takáč, Zdenko; Santiago, Regivan; Bustince Sola, Humberto

; Fernández Fernández, Francisco Javier

; Pereira Dimuro, Graçaliz

(IEEE, 2022) Artículo / Artikulua

Automatic image detection is one of the most im- portant areas in computing due to its potential application in numerous real-world scenarios. One important tool to deal with that is called overlap indices. They were ...
