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 ... -
Geology-based and ecological processes of divergence between and within species of wingless darkling beetles
Aim: Discerning the relative role of geographical and ecological factors in promoting diversification is central to our understanding of the origin and maintenance of biodiversity. We explore the roles of geology and ... -
Geometric multigrid methods for Darcy–Forchheimer flow in fractured porous media
In this paper, we present a monolithic multigrid method for the efficient solution of flow problems in fractured porous media. Specifically, we consider a mixed-dimensional model which couples Darcy flow in the porous ... -
Geometrical aggregation of finite fuzzy sets
A fuzzy set on a finite universe can be interpreted as a vector in a unit cube. This gives rise to a huge variety of approaches in order to aggregate finite fuzzy sets or to modify a given one. We analyze several geometrical ... -
Gongora-ko (Nafarroa) Jauregizaharra jauregiaren datazio dendrokronologikoa
En este trabajo se presenta la datación dendrocronológica del palacio Jauregizaharra de Gongora (Navarra). Desde el aspecto dendrocronológico se han construido 3 cronologías de referencia, y, desde el punto de vista de la ... -
Greedy approximation for biorthogonal systems in quasi-Banach spaces
The general problem addressed in this work is the development of a systematic study of the thresholding greedy algorithm for general biorthogonal systems in quasi-Banach spaces from a functional-analytic point of view. If ... -
Hand-as-a-prop: using the hand as a haptic proxy for manipulation in virtual reality
Haptic feedback can be almost as important as visual information in virtual reality environments. On the one hand, in Active Haptic Feedback, specialized devices such as vibrotactile gloves are employed; however, these ... -
Helping people with language learning disabilities using native mobile voice recognition: exploring its limits and advantages
This article presents an intelligent system for people with language learning disabilities called MarLuc. MarLuc aims to improve people’s skills in their native language rather than a second language. The system was born ... -
The hidden value of intangibles: do CEO characteristics matter?
Purpose: A great deal of research has examined the relationship between a single CEO attribute and a single measure of firm performance; no attempts have been made to integrate them to create a more global vision of both. ... -
Hierarchical spatio-temporal change-point detection
Detecting change-points in multivariate settings is usually carried out by analyzing all marginals either independently, via univariate methods, or jointly, through multivariate approaches. The former discards any inherent ... -
High temperature and water deficit cause epigenetic changes in somatic plants of Pinus radiata D. Don
Current climate changes imply an imminent risk for forest species. In this context, somatic embryogenesis is a valuable tool to study the response of plants to different abiotic stresses. Based on this, we applied a ... -
High-dimensional order-free multivariate spatial disease mapping
Despite the amount of research on disease mapping in recent years, the use of multivariate models for areal spatial data remains limited due to difficulties in implementation and computational burden. These problems are ... -
HIL flight simulator for VTOL-UAV pilot training using X-plane
With the increasing popularity of vertical take-off and landing unmanned aerial vehicles (VTOL UAVs), a new problem arises: pilot training. Most conventional pilot training simulators are designed for full-scale aircrafts, ... -
Holistic Architecture for Music Education: A research design for carrying out empiric and interdisciplinary studies in didactics of music
Los temas estéticos de la música son relevantes en la investigación de la educación musical, pero otros elementos vinculados a las ciencias sociales también desempeñan un papel central, como las relaciones entre compañeros ... -
How important is family involvement for small companies’ growth?
Purpose: Our paper seeks to further understand how family involvement in management influences firm growth. Design/methodology/approach: Using a sample of small high-tech firms, we classify three different types of firms: ...
