General overlap functions
Miguel Turullols, Laura de
; Gómez, Daniel; Tinguaro, Javier; Montero, Javier; Bustince Sola, Humberto ; Pereira Dimuro, Graçaliz ; Sanz, Jose Antonio (Elsevier, 2019)
Artículo / Artikulua 
As a generalization of bivariate overlap functions, which measure the degree of overlapping (intersection for non-crisp sets) of n different classes, in this paper we introduce the concept of general overlap functions. We ... -
Motor-imagery-based brain-computer interface using signal derivation and aggregation functions
Fumanal Idocin, Javier ; Wang, Yu-Kai; Lin, Chin-Teng; Fernández Fernández, Francisco Javier ; Sanz Delgado, José Antonio ; Bustince Sola, Humberto (IEEE, 2021)
Artículo / Artikulua
Brain Computer Interface (BCI) technologies are popular methods of communication between the human brain and external devices. One of the most popular approaches to BCI is Motor Imagery (MI). In BCI applications, the ... -
On fuzzy implications derived from general overlap functions and their relation to other classes
Pinheiro, Jocivania; Santos, Helida; Pereira Dimuro, Graçaliz; Bedregal, Benjamin ; Santiago, Regivan; Fernández Fernández, Francisco Javier ; Bustince Sola, Humberto (MDPI, 2023)
Artículo / Artikulua
There are distinct techniques to generate fuzzy implication functions. Despite most of them using the combination of associative aggregators and fuzzy negations, other connectives such as (general) overlap/grouping ... -
A proposal for tuning the α parameter in CαC-integrals for application in fuzzy rule-based classification systems
Lucca, Giancarlo; Sanz Delgado, José Antonio ; Pereira Dimuro, Graçaliz ; Bedregal, Benjamin ; Bustince Sola, Humberto (Springer, 2020)
Artículo / Artikulua
In this paper, we consider the concept of extended Choquet integral generalized by a copula, called CC-integral. In particular, we adopt a CC-integral that uses a copula defined by a parameter α, which behavior was tested ... -
A study of OWA operators learned in convolutional neural networks
Domínguez Catena, Iris ; Paternain Dallo, Daniel ; Galar Idoate, Mikel (MDPI, 2021)
Artículo / Artikulua
Ordered Weighted Averaging (OWA) operators have been integrated in Convolutional Neural Networks (CNNs) for image classification through the OWA layer. This layer lets the CNN integrate global information about the image ... -
Towards interval uncertainty propagation control in bivariate aggregation processes and the introduction of width-limited interval-valued overlap functions
Asmus, Tiago ; Pereira Dimuro, Graçaliz ; Bedregal, Benjamin ; Sanz Delgado, José Antonio ; Mesiar, Radko; Bustince Sola, Humberto (Elsevier, 2021)
Artículo / Artikulua
Overlap functions are a class of aggregation functions that measure the overlapping degree between two values. They have been successfully applied as a fuzzy conjunction operation in several problems in which associativity ... -
Unbalanced interval-valued OWA operators
Miguel Turullols, Laura de ; Bustince Sola, Humberto ; Barrenechea Tartas, Edurne ; Pagola Barrio, Miguel ; Fernández Fernández, Francisco Javier (Springer Berlin Heidelberg, 2016)
Artículo / Artikulua
In this work, we introduce a new class of functions defned on the interval-valued setting. These functions extend classical OWA operators but allow for diferent weighting vectors to handle the lower bounds and the ...
