A bias correction function for classification performance assessment in two-class imbalanced problems
Elsevier (2014)This paper introduces a framework that allows to mitigate the impact of class imbalance on most scalar performance measures when used to evaluate the behavior of classifiers. Formally, a correction function is defined with ... -
Classifiers ensemble in remote sensing: a comparative analysis
Universitat Jaume I (2014-04)Land Cover and Land Use (LCLU) maps are very important tools for understanding the relationships between human activities and the natural environment. Defining accurately all the features over the Earth's surface is ... -
Evaluation and improvement of road vehicle pollutant emission factors based on instantaneous emissions data processing
Universitat Jaume I (2014-06-09)<p>Introduction<br/> Current instrumentation makes it possible to measure vehicle emissions with high temporal resolution. But the increased resolution of emissions signals does not equate with increased accuracy. A ... -
General Framework for Deriving Reproducible Krylov Subspace Algorithms: BiCGStab Case
Springer (2023)Parallel implementations of Krylov subspace algorithms often help to accelerate the procedure to find the solution of a linear system. However, from the other side, such parallelization coupled with asynchronous and ... -
General framework for re-assuring numerical reliability in parallel Krylov solvers: A case of bi-conjugate gradient stabilized methods
SAGE Publications Inc. (2024-01-01)Parallel implementations of Krylov subspace methods often help to accelerate the procedure of finding an approximate solution of a linear system. However, such parallelization coupled with asynchronous and out-of-order ... -
Hierarchical approach for deriving a reproducible unblocked LU factorization
Sage (2019-03-17)We propose a reproducible variant of the unblocked LU factorization for graphics processor units (GPUs). For this purpose, we build upon Level-1/2 BLAS kernels that deliver correctly-rounded and reproducible results for ... -
Impartiality and accuracy as a case in point while interpreting in a refugee context
John Benjamins Publishing (2020-11-11)This paper examines the fundamentals of professionalism focusing on the code of ethics as a pivotal parameter. Attention is paid to the difficulties of implementing two of the core principles of codes of ethics for ... -
La persisitencia de las dificultades lectoras desde Educación Infantil a Educación Primaria
Universitat Jaume I (2015-06)Este estudio tiene como finalidad investigar los inicios de la lectura de dos grupos de niños-as con dificultades, por un lado, en conocimiento de letras y lectura de palabras y, por otro, únicamente con dificultades en ... -
Predicción de la reincidencia delictiva en menores infractores
Asociación Nacional de Psicología Evolutiva y Educativa de la Infancia, Adolescencia y Mayores (INFAD) (2009)The criminal recidivism is one of the main worries of our society and its prediction is an important need in the research field, mainly in minors (Andrews & Bonta, 2006). This study tries to analyse the internal consistency ... -
Reproducibility of parallel preconditioned conjugate gradient in hybrid programming environments
Sage (2020-06-17)The Preconditioned Conjugate Gradient method is often employed for the solution of linear systems of equations arising in numerical simulations of physical phenomena. While being widely used, the solver is also known for ... -
Reproducibility strategies for parallel Preconditioned Conjugate Gradient
Elsevier (2020-01-02)The Preconditioned Conjugate Gradient method is often used in numerical simulations. While being widely used, the solver is also known for its lack of accuracy while computing the residual. In this article, we aim at a ... -
Spatio-temporal pattern mining from global positioning systems (GPS) trajectories dataset
Universitat Jaume I (2015-08)The increasing frequency of use location-acquisition technology like the Global Positioning System is leading to the collection of large spatio-temporal datasets. The prospect of discovering usable knowledge about movement ... -
Validity of a simple videogrammetric method to measure the movement of all hand segments for clinical purposes
SAGE Publications (2014)Hand movement measurement is important in clinical, ergonomics and biomechanical fields. Videogrammetric techniques allow the measurement of hand movement without interfering the natural hand behaviour. However, an ...
