F-homogeneous functions and a generalization of directional monotonicity
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 ... -
Factores de gestión del conocimiento en entidad pública del sector de tránsito y transporte
Desde una visión sistémica, la gestión del conocimiento afecta al proceso de toma de decisiones en las organizaciones que, en un entorno globalizado, deben plantear estrategias que posibiliten el incremento de la competitividad ... -
Filling missing data and smoothing altered data in satellite imagery with a spatial functional procedure
Outliers and missing data are commonly found in satellite imagery. These are usually caused by atmospheric or electronic failures, hampering the correct monitoring of remote-sensing data. To avoid distorted data, we propose ... -
Fireballs recorded between May and July 2021 by the Southwestern Europe Meteor Network
This work focuses on the analysis of the most remarkable bolides recorded over the Iberian Peninsula and neighboring areas in the framework of the Southwestern Europe Meteor Network (SWEMN) and the SMART project. These ... -
Flexible Bayesian P-splines for smoothing age-specific spatio-temporal mortality patterns
In this paper age-space-time models based on one and two-dimensional P-splines with B-spline bases are proposed for smoothing mortality rates, where both xed relative scale and scale invariant two-dimensional penalties ... -
A framework for generalized monotonicity of fusion functions
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 ... -
FRIPON: a worldwide network to track incoming meteoroids
Context. Until recently, camera networks designed for monitoring fireballs worldwide were not fully automated, implying that in case of a meteorite fall, the recovery campaign was rarely immediate. This was an important ... -
From fuzzy sets to interval-valued and Atanassov intuitionistic fuzzy sets: a unified view of different axiomatic measures
We examine a broad collection of axiomatic definitions from various and diverse contexts, within the domain of fuzzy sets. We evaluate their respective extensions to the case of interval-valued fuzzy sets and intuitionistic ... -
From restricted equivalence functions on Ln to similarity measures between fuzzy multisets
Restricted equivalence functions are well-known functions to compare two numbers in the interval between 0 and 1. Despite the numerous works studying the properties of restricted equivalence functions and their multiple ... -
Las funciones docentes: su enseñanza y aprendizaje en los grados en maestro
La experiencia docente universitaria en los Grados en Maestro demuestra que existen obstáculos didácticos para la enseñanza y aprendizaje de las competencias asociadas a las funciones y prácticas docentes requeridas en la ... -
Funções de agregação baseadas em integral de Choquet aplicadas em redimensionalização de imagens
The increasing data volume, coupled with the high complexity of these data, has generated the need to develop increasingly efficient knowledge extraction techniques, both in computational cost and precision. Most of the ... -
A fusion method for multi-valued data
In this paper we propose an extension of the notion of deviation-based aggregation function tailored to aggregate multidimensional data. Our objective is both to improve the results obtained by other methods that try to ... -
FUZZ-EQ: a data equalizer for boosting the discrimination power of fuzzy classifiers
The definition of linguistic terms is a critical part of the construction of any fuzzy classifier. Fuzzy partitioning methods (FPMs) range from simple uniform partitioning to sophisticated optimization algorithms. In this ... -
Fuzzy Arrovian theorems when preferences are strongly-connected
In this paper we study the aggregation of fuzzy preferences on non-necessarily finite societies. We characterize in terms of possibility and impossibility a family of models of strongly-connected preferences in which the ... -
A fuzzy association rule-based classifier for imbalanced classification problems
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 ... -
A fuzzy methodology for approaching fuzzy sets of the real line by fuzzy numbers
In 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. ... -
A generalization of the Choquet integral defined in terms of the Mobius transform
In this article, we propose a generalization of the Choquet integral, starting fromits definition in terms of the Mobius transform. We modify the product on R considered in the Lovasz extension form of the Choquet integral ... -
Generalized decomposition integral
In this paper we propose two different generalizations of the decomposition integral introduced by Even and Lehrer. We modify the product operator merging a given capacity and the decomposition coefficients by some more ... -
Generalizing max pooling via (a, b)-grouping functions for convolutional neural networks
Due to their high adaptability to varied settings and effective optimization algorithm, Convolutional Neural Networks (CNNs) have set the state-of-the-art on image processing jobs for the previous decade. CNNs work in a ... -
Generating airborne ultrasonic amplitude patterns using an open hardware phased array
Holographic methods from optics can be adapted to acoustics for enabling novel applications in particle manipulation or patterning by generating dynamic custom-tailored acoustic fields. Here, we present three contributions ...
