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 ... -
Directional monotonicity of multidimensional fusion functions with respect to admissible orders
Sesma Sara, Mikel ; Bustince Sola, Humberto ; Mesiar, Radko (Elsevier, 2023)
Artículo / Artikulua
The notion of directional monotonicity emerged as a relaxation of the monotonicity condition of aggregation functions. As the extension of aggregation functions to fuse more complex information than numeric data, directional ... -
F-homogeneous functions and a generalization of directional monotonicity
Santiago, Regivan; Sesma Sara, Mikel ; Fernández Fernández, Francisco Javier ; Takáč, Zdenko; Mesiar, Radko; Bustince Sola, Humberto (Wiley, 2022)
Artículo / Artikulua
A function that takes (Formula presented.) numbers as input and outputs one number is said to be homogeneous whenever the result of multiplying each input by a certain factor (Formula presented.) yields the original output ... -
A framework for generalized monotonicity of fusion functions
Sesma Sara, Mikel ; Šeliga, Adam; Boczek, Michał; Jin, LeSheng; Kaluszka, Marek; Kalina, Martin; Bustince Sola, Humberto ; Mesiar, Radko (Elsevier, 2023)
Artículo / Artikulua
The relaxation of the property of monotonicity is a trend in the theory of aggregation and fusion functions and several generalized forms of monotonicity have been introduced, most of which are based on the notion of ... -
A fuzzy association rule-based classifier for imbalanced classification problems
Sanz Delgado, José Antonio ; Sesma Sara, Mikel ; Bustince Sola, Humberto (Elsevier, 2021)
Artículo / Artikulua
Imbalanced classification problems are attracting the attention of the research community because they are prevalent in real-world problems and they impose extra difficulties for learning methods. Fuzzy rule-based ... -
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. ... -
The law of O-conditionality for fuzzy implications constructed from overlap and grouping functions
Pereira Dimuro, Graçaliz ; Bedregal, Benjamin ; Fernández Fernández, Francisco Javier ; Sesma Sara, Mikel ; Pintor Borobia, Jesús María ; Bustince Sola, Humberto (Elsevier, 2019)
Artículo / Artikulua
Overlap and grouping functions are special kinds of non necessarily associative aggregation operators proposed for many applications, mainly when the associativity property is not strongly required. The classes of overlap ... -
Measures of embedding for interval-valued fuzzy sets
Bouchet, Agustina; Sesma Sara, Mikel ; Ochoa Lezaun, Gustavo ; Bustince Sola, Humberto ; Montes, Susana; Díaz, Irene (Elsevier, 2023)
Artículo / Artikulua
Interval-valued fuzzy sets are a generalization of classical fuzzy sets where the membership values are intervals. The epistemic interpretation of interval-valued fuzzy sets assumes that there is one real-valued membership ... -
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 ... -
Trend analysis in L-fuzzy contexts with absent values
Alcalde, Cristina; Burusco Juandeaburre, Ana ; Bustince Sola, Humberto ; Sesma Sara, Mikel (University of Sistan and Baluchestan (Irán), 2020)
Artículo / Artikulua
Sometimes we have to work with L-fuzzy context sequences where one or more values are missing. These sequences can represent, among other things, the evolution in time of an L-fuzzy context. The studies of tendencies that ... -
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 ...
