Dynamic selection of the best base classifier in one versus one
(Elsevier, 2015-05-19)Class binarization strategies decompose the original multi-class problem into several binary sub-problems. One versus One (OVO) is one of the most popular class binarization techniques, which considers every pair of classes ... -
Evaluation of two virtual cursors for assisting web access to people with motor impairments
(Elsevier, 2019-08-02)People with motor impairments (MI) may face accessibility barriers when using computers due to their health conditions and therefore need to use alternative devices to a standard mouse for pointing and clicking in graphical ... -
Evolving Gaussian process kernels from elementary mathematical expressions for time series extrapolation
(Elsevier, 2021-10-28)[EN]Choosing the best kernel is crucial in many Machine Learning applications. Gaussian Processes are a state-of-the-art technique for regression and classification that heavily relies on a kernel function. However, in the ... -
Ideal and Predictable Hit Ratio for Matrix Transposition in Data Caches
(MDPI, 2020-02-03)Matrix transposition is a fundamental operation, but it may present a very low and hardly predictable data cache hit ratio for large matrices. Safe (worst-case) hit ratio predictability is required in real-time systems. ... -
Inclusive Web Empirical Studies in Remote and In-Situ Settings: A User Evaluation of the RemoTest Platform
(Taylor & Francis, 2019-04-21)Web accessibility evaluation requires tests to be carried out with real users with disabilities performing real tasks or activities. To recruit an appropriate group of users and to observe their performance in the real ... -
JolasMATIKA: An Experience for Teaching and Learning Computing Topics From University to Primary Education
(IEEE, 2020-08)Contribution: A learning-by-teaching methodology through games can be used to promote informatics (computer science) in primary and secondary education. Applying the proposed activities can change students' perception of ... -
Kernel density estimation in accelerators: Implementation and performance evaluation
(ACM, 2016-02-01)Kernel density estimation (KDE) is a popular technique used to estimate the probability density function of a random variable. KDE is considered a fundamental data smoothing algorithm, and it is a common building block in ... -
Large Scale Linguistic Processing of Tweets to Understand Social Interactions among Speakers of Less Resourced Languages: The Basque Case
(MDPI, 2019-06-13)Social networks like Twitter are increasingly important in the creation of new ways of communication. They have also become useful tools for social and linguistic research due to the massive amounts of public textual data ... -
Longitudinal Study of Two Virtual Cursors for People With Motor Impairments: A Performance and Satisfaction Analysis on Web Navigation
(IEEE, 2020)The lack of dexterity in the upper limbs of people with motor impairments may prevent the use of standard pointing devices, such as mice, to access graphical user interfaces. In these cases, pointing and clicking are usually ... -
Mateda-2.0: Estimation of Distribution Algorithms in MATLAB
(Journal of Statistical Software, UCLA Dept. Statistics, 2010-07)This paper describes Mateda-2.0, a MATLAB package for estimation of distribution algorithms (EDAs). This package can be used to solve single and multi-objective discrete and continuous optimization problems using EDAs based ... -
Measuring Language Distance of Isolated European Languages
(MDPI, 2020-03-27)Phylogenetics is a sub-field of historical linguistics whose aim is to classify a group of languages by considering their distances within a rooted tree that stands for their historical evolution. A few European languages ... -
Multi-objective environmental model evaluation by means of multidimensional kernel density estimators: Efficient and multi-core implementations
(2015-01-01)We propose an extension to multiple dimensions of the univariate index of agreement between Probability Density Functions (PDFs) used in climate studies. We also provide a set of high-performance programs targeted both to ... -
Multilingual audio information management system based on semantic knowledge in complex environments
(Springer, 2020)This paper proposes a multilingual audio information management system based on semantic knowledge in complex environments. The complex environment is defined by the limited resources (financial, material, human, and audio ... -
NewOneVersusOneAll method: NOV@
(Elsevier, 2014-04-19)Binarization strategies decompose the original multi-class dataset into multiple two-class subsets, learning a different binary model for each new subset. One-vs-All (OVA) and One-vs-One (OVO) are two of the most well-known ... -
On the Analysis of Speech and Disfluencies for Automatic Detection of Mild Cognitive Impairment
(Springer, 2020-10)Alzheimer's disease is characterized by a progressive and irreversible cognitive deterioration. In a previous stage, the so-called Mild Cognitive Impairment or cognitive loss appears. Nevertheless, this previous stage does ... -
PCTBagging: From inner ensembles to ensembles. A trade-off between discriminating capacity and interpretability
(Elsevier, 2022-01)[EN] The use of decision trees considerably improves the discriminating capacity of ensemble classifiers. However, this process results in the classifiers no longer being interpretable, although comprehensibility is a ... -
Reducing the WCET and analysis time of systems with simple lockable instruction caches
(Plos One, 2020-01)One of the key challenges in real-time systems is the analysis of the memory hierarchy. Many Worst-Case Execution Time (WCET) analysis methods supporting an instruction cache are based on iterative or convergence algorithms, ... -
Routing in MobileWireless Sensor Networks: A Leader-Based Approach
(MDPI, 2017-07)This paper presents a leader-based approach to routing in Mobile Wireless Sensor Networks (MWSN). Using local information from neighbour nodes, a leader election mechanism maintains a spanning tree in order to provide the ... -
Smart Meeting Room Usage Information and Prediction by Modelling Occupancy Profiles
(MDPI, 2019-01-02)The monitoring of small houses and rooms has become possible due to the advances in IoT sensors, actuators and low power communication protocols in the last few years. As buildings are one of the biggest energy consuming ... -
Towards a standard methodology to evaluate internal cluster validity indices
(Elsevier, 2011-02-01)The evaluation and comparison of internal cluster validity indices is a critical problem in the clustering area. The methodology used in most of the evaluations assumes that the clustering algorithms work correctly. We ...
