On the influence of admissible orders in IVOVO
Uriz Martín, Mikel Xabier
; Paternain Dallo, Daniel ; Bustince Sola, Humberto ; Galar Idoate, Mikel (Springer, 2019)
Contribución a congreso / Biltzarrerako ekarpena 
It is known that when dealing with interval-valued data, there exist problems associated with the non-existence of a total order. In this work we investigate a reformulation of an interval-valued decomposition strategy for ... -
On the influence of interval normalization in IVOVO fuzzy multi-class classifier

Artículo / Artikulua
One of the main results of the article Gelfand theory for real Banach algebras, recently published in [Rev R Acad Cienc Exactas Fís Nat Ser A Mat RACSAM 114(4):163, 2020] is Proposition 4.1, which establishes that the norm ... -
On the normalization of interval data
Santiago, Regivan; Bergamaschi, Flaulles; Bustince Sola, Humberto ; Pereira Dimuro, Graçaliz ; Asmus, Tiago ; Sanz Delgado, José Antonio (MDPI, 2020)
Artículo / Artikulua
The impreciseness of numeric input data can be expressed by intervals. On the other hand, the normalization of numeric data is a usual process in many applications. How do we match the normalization with impreciseness on ... -
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 ... -
On the performances of trend and change-point detection methods for remote sensing data
Militino, Ana F. ; Moradi, Mohammad Mehdi ; Ugarte Martínez, María Dolores (MDPI, 2020)
Artículo / Artikulua
Detecting change-points and trends are common tasks in the analysis of remote sensing data. Over the years, many different methods have been proposed for those purposes, including (modified) Mann-Kendall and Cox-Stuart ... -
On the permutative equivalence of squares of unconditional bases
Albiac Alesanco, Fernando José ; Ansorena, José L. (Elsevier, 2022)
Artículo / Artikulua
We prove that if the squares of two unconditional bases are equivalent up to a permutation, then the bases themselves are permutatively equivalent. This settles a twenty-five year-old question raised by Casazza and Kalton ... -
On the role of distance transformations in Baddeley's Delta Metric
López Molina, Carlos ; Iglesias Rey, Sara ; Bustince Sola, Humberto ; Baets, Bernard de (Elsevier, 2021)
Artículo / Artikulua
Comparison and similarity measurement have been a key topic in computer vision for a long time. There is, indeed, an extensive list of algorithms and measures for image or subimage comparison. The superiority or inferiority ... -
Online relative risks/rates estimation in spatial and spatio-temporal disease mapping
Adin Urtasun, Aritz ; Goicoa Mangado, Tomás ; Ugarte Martínez, María Dolores (Elsevier, 2019)
Artículo / Artikulua
Background and objective: Spatial and spatio-temporal analyses of count data are crucial in epidemiology and other fields to unveil spatial and spatio-temporal patterns of incidence and/or mortality risks. However, fitting ... -
Onto-semiotic analysis of diagrammatic reasoning
Giacomone, Belén; Godino, Juan D.; Blanco, Teresa F.; Wilhelmi, Miguel R. (Springer, 2022)
Artículo / Artikulua
Diagrams and in general the use of visualization and manipulative material play an important role in mathematics teaching and learning processes. Although several authors warn that mathematics objects should be distinguished ... -
An ontology-based system to avoid UAS flight conflicts and collisions in dense traffic scenarios
Martín Lammerding, David; Astrain Escola, José Javier ; Córdoba Izaguirre, Alberto; Villadangos Alonso, Jesús (Elsevier, 2023)
Artículo / Artikulua
New Unmanned Aerial Systems (UAS) applications will increase air traffic densities in metropolitan regions. Collision avoidance systems (CAS) are a key component in integrating a high number of UAS into the airspace in a ... -
