A Novel Low-Cost Sensor Prototype for Monitoring Temperature during Wine Fermentation in Tanks
(MDPI, 2013)This paper presents a multipurpose and low cost sensor for temperature control over the wine fermentation process, in order to steadily communicate data through wireless modules in real time to a viticulturist’s mobile ... -
A Ubiquitous NFC Solution for the Development of Tailored Marketing Strategies Based on Discount Vouchers and Loyalty Cards
(MDPI, 2013)Because of the global economic turmoil, nowadays a lot of companies are adopting a “deal of the day” business model, some of them with great success. Generally, they try to attract and retain customers through discount ... -
Human interaction categorization by using audio-visual cues
(Springer Nature, 2013)Human Interaction Recognition (HIR) in uncontrolled TV video material is a very challenging problem because of the huge intra-class variability of the classes (due to large differences in the way actions are performed, ... -
Multifractal detrended fluctuation analysis of sheep livestock prices in origin
(Elsevier, 2013)The multifractal detrended fluctuation analysis (MF-DFA) is used to verify whether or not the returns of time series of prices paid to farmers in original markets can be described by the multifractal approach. By way of ... -
Exploitation of Pairwise Class Distances for Ordinal Classification
(2013-07-15)Ordinal classification refers to classification problems in which the classes have a natural order imposed on them because of the nature of the concept studied. Some ordinal classification approaches perform a projection ... -
Algoritmos de aprendizaje evolutivo y estadístico para la determinación de mapas de malas hierbas utilizando técnicas de teledetección
(2013-10-08)Este trabajo aborda la resolución de problemas de clasificación binaria utilizando una metodología híbrida que combina la regresión logística y modelos evolutivos de redes neuronales de unidades producto. Para estimar ... -
Projection based ensemble learning for ordinal regression
(2013-10-08)The classification of patterns into naturally ordered labels is referred to as ordinal regression. This paper proposes an ensemble methodology specifically adapted to this type of problems, which is based on computing ... -
An ubiquitous and non intrusive system for pervasive advertising using NFC and geolocation technologies and air hand gestures
(Hindawi, 2014)In this paper we present a pervasive proposal for advertising using mobile phones, Near Field Communication, geolocation and air hand gestures. Advertising post built by users in public/private spaces can store multiple ... -
Effects of Molecular Representation in Predicting the Biological Activity using SVM and PLS Approaches
(2014)In this work we study and analyze the behavior of different representational spaces for molecular activity prediction. Representational spaces based on fingerprint similarity, structural similarity using maximum ... -
Reducing gaps in quantitative association rules: A genetic programming free-parameter algorithm
(IOS Press, 2014)The extraction of useful information for decision making is a challenge in many different domains. Association rule mining is one of the most important techniques in this field, discovering relationships of interest among ... -
Object-Based Image Classification of Summer Crops with Machine Learning Methods
(MDPI, 2014)The strategic management of agricultural lands involves crop field monitoring each year. Crop discrimination via remote sensing is a complex task, especially if different crops have a similar spectral response and cropping ... -
A Classification Module for Genetic Programming Algorithms in JCLEC
(MIT Press, 2014)JCLEC-Classi cation is a usable and extensible open source library for genetic program- ming classi cation algorithms. It houses implementations of rule-based methods for clas- si cation based on genetic programming, ... -
Comparing Evolutionary Algorithms and Particle Filters for Markerless Human Motion Capture
(Elsevier, 2014)Markerless Human Motion Capture is the problem of determining the joints’ angles of a three-dimensional articulated body model that best matches current and past observations acquired by video cameras. The problem of ... -
Teaching push-down automata and Turing machines
(2014-02-27)In this paper we present the new version of a tool to assist in teaching formal languages and automata theory. In the previous version the tool provided algorithms for regular expressions, finite automata and context ... -
Utilización de un sistema de captura de movimiento 3D para el análisis cienemático del gesto técnico del paso de vallas
(2014-02-27)La carrera de vallas es una de las disciplinas más técnicas del atletismo. Consiste en una combinación cíclica de sprint y salto donde el mayor interés para entrenador y atleta es analizar y perfeccionar el estilo del paso ... -
JCLEC Meets WEKA!
(2014-02-27)WEKA has recently become a very referenced DM tool. In spite of all the functionality it provides, it does not include any framework for the development of evolutionary algorithms. An evolutionary computation framework ... -
A weed monitoring system using UAV-imagery and the Hough transform
(2015)Usually, crops require the use of herbicides as a useful manner of controlling the quality and quantity of crop production. Although there are weed-free areas, the most common approach is to broadcast herbicides entirely ...
