Improving the performance of fuzzy rule-based classification systems based on a nonaveraging generalization of CC-integrals named C-F1F2-integrals
Lucca, Giancarlo; Pereira Dimuro, Graçaliz
; Fernández Fernández, Francisco Javier ; Bustince Sola, Humberto ; Bedregal, Benjamin; Sanz Delgado, José Antonio (IEEE, 2019)
Artículo / Artikulua 
A key component of fuzzy rule-based classification systems (FRBCS) is the fuzzy reasoning method (FRM) since it infers the class predicted for new examples. A crucial stage in any FRM is the way in which the information ... -

Artículo / Artikulua
Aggregation or fusion of interval data is not a trivial task, since the necessity of arranging data arises in many aggregation functions, such as OWA operators or the Choquet integral. Some arranging procedures have been ... -

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 ... -
Mixture functions and their monotonicity
Špirková, Jana; Beliakov, Gleb; Bustince Sola, Humberto ; Fernández Fernández, Francisco Javier (Elsevier, 2019)

In this paper, we consider multipoint flux mixed finite element discretizations for slightly compressible Darcy flow in porous media. The methods are formulated on general meshes composed of triangles, quadrilaterals, ... -
Normalization through invariants in n-dimensional Kepler problems
Meyer, Kenneth Ray; Palacián Subiela, Jesús Francisco; Yanguas Sayas, Patricia (Pleiades Publishing, 2018)
Artículo / Artikulua
We present a procedure for the normalization of perturbed Keplerian problems in n dimensions based on Moser regularization of the Kepler problem and the invariants associated to the reduction process. The approach allows ... -
The null space of fuzzy inclusion measures
Couso, Inés; Bustince Sola, Humberto; Fernández Fernández, Francisco Javier ; Sánchez, Luciano (IEEE, 2019)
Artículo / Artikulua
Some formal relationships between the different axiomatic definitions of inclusion measure are analysed. In particular, the links between the different proposals about the null-space (the collection of pairs associated ... -
On a particular class of Meijer's G functions appearing in fractional calculus

Artículo / Artikulua
In this paper we investigate the Meijer G-function G p+1,p+1 p,1 which, for certain parameter values, represents the Riemann-Liouville fractional integral of the Meijer-Nørlund function G p,p. p,0 The properties of this ... -
On co-orbital quasi-periodic motion in the three-body problem

Artículo / Artikulua
Within the framework of the planar three-body problem we establish the existence of quasi-periodic motions and KAM 4-tori related to the co-orbital motion of two small moons about a large planet where the moons move in ... -
On fixed point theory in partially ordered sets and an application to asymptotic complexity of algorithms
Estevan Muguerza, Asier; Miñana, Juan José; Valero, Óscar (Springer, 2019)
Artículo / Artikulua
The celebrated Kleene fixed point theorem is crucial in the mathematical modelling of recursive specifications in Denotational Semantics. In this paper we discuss whether the hypothesis of the aforementioned result can be ... -
