Affine construction methodology of aggregation functions
Roldán López de Hierro, Antonio Francisco; Roldán, Concepción; Bustince Sola, Humberto ; Fernández Fernández, Francisco Javier ; Rodríguez Martínez, Iosu ; Fardoun, Habib; Lafuente López, Julio (Elsevier, 2020) Artículo / ArtikuluaAggregation 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 ; Špirková, Jana; Lafuente López, Julio ; Pradera, Ana; Mesiar, Radko; Bustince Sola, Humberto (Taylor & Francis, 2019) Artículo / ArtikuluaIn 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 ... -
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 / ArtikuluaIn 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 / ArtikuluaIn 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 / ArtikuluaIn 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 / ArtikuluaSocial 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 / ArtikuluaIn 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 / ArtikuluaAutomatic 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 ...
