1920-2015: un siglo de Visión por Computador
(Universidad de Córdoba, 2015)Dentro de 5 años se cumplirá exactamente un siglo desde la aparición de esta Ciencia a la que aún seguimos refiriéndonos como Visión por Computador. A diferencia de otras Ciencias, con mucha más tradición, conocemos ... -
A guided data projection technique for classi cation of sovereign ratings: the case of European Union 27
(2017-01-20)Sovereign rating has had an increasing importance since the beginning of the nancial crisis. However, credit rating agencies opacity has been criticised by several authors highlighting the suitability of designing more ... -
A Methodology for Buildings Access to Solar Radiation in Sustainable Cities
(MDPI, 2019)The growing need to improve the environmental and energy sustainability of buildings involves the use of solar radiation incident on their surfaces. However, in cities, this task is complicated due to the constructive ... -
A new approach for multi-view gait recognition on unconstrained paths
(2017)Direction changes cause di culties for most of the gait recognition systems, due to appearance changes. We propose a new approach for multi-view gait recognition, which focuses on recognizing people walking on unconstrained ... -
A New Clustering Algorithm Based on Pattern Extraction in Molecular Fingerprints
(2017-12-11)In this paper an algorithm for the extraction of patterns in chemical fingerprints is described. As input this algorithm uses a fingerprint representation of the molecule dataset, generating a group of consistent disjoint ... -
A new thresholding approach for automatic generation of polygonal approximations
(Elsevier, 2016)The present paper proposes a new algorithm for automatic generation of polygonal approximations of 2D closed contours based on a new thresholding method. The new proposal computes the signi cance level of the contour points ... -
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 Review of Classification Problems and Algorithms in Renewable Energy Applications
(MDPI, 2016)Classification problems and their corresponding solving approaches constitute one of the fields of machine learning. The application of classification schemes in Renewable Energy (RE) has gained significant attention in ... -
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 ... -
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 ... -
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 ... -

(Universidad de Castilla-La Mancha, Escuela Superior de Informática, 2005)Este artículo muestra la utilización de los algoritmos evolutivos para el descubrimiento de reglas de predicción que se utilizarán en la mejora de Cursos Hipermedia Adaptativos basados en Web. Se ha desarrollado una ... -
Algoritmos genéticos locales
(Universidad de Málaga, 2007)Los Algoritmos Genéticos Locales son procedimientos que iterativamente re nan soluciones dadas. Su diferencia con procedimientos de mejora iterativa clásicos reside en el uso de operadores genéticos para realizar el ... -
An Alert System for People Monitoring Based on Multi- Agents using Maps
(Technische Universität Graz, 2013)This paper describes an alert system for people monitoring based on multi-agent using maps. This system monitors the users’ physical context using their mobile phone. The data acquisition is made using the available ... -
An Automatic Programming ACO-Based Algorithm for Classification Rule Mining
(2017-01-20)In this paper we present a novel algorithm, named GBAP, that jointly uses automatic programming with ant colony optimization for mining classification rules. GBAP is based on a context-free grammar that properly guides ... -
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 ... -
