Speeding up Multiple Instance Learning Classification Rules on GPUs
(2017)Multiple instance learning is a challenging task in supervised learning and data mining. How- ever, algorithm performance becomes slow when learning from large-scale and high-dimensional data sets. Graphics processing ... -
sSLAM: Speeded-Up Visual SLAM Mixing Artificial Markers and Temporary Keypoints
(MDPI, 2023)Environment landmarks are generally employed by visual SLAM (vSLAM) methods in the form of keypoints. However, these landmarks are unstable over time because they belong to areas that tend to change, e.g., shadows or moving ... -

(MDPI, 2016)The current social impact of new technologies has produced major changes in all areas of society, creating the concept of a smart city supported by an electronic infrastructure, telecommunications and information technology. ... -
Stereo Pictorial Structure for 2D Articulated Human Pose Estimation
(2015)In this paper, we consider the problem of 2D human pose estimation on stereo image pairs. In particular, we aim at estimating the location, orientation and scale of upper-body parts of people detected in stereo image ... -
Study of the Applicability Domain of the QSAR Classification Models by Means of the Rivality and Modelability Indexes
(MDPI, 2018)The reliability of a QSAR classification model depends on its capacity to achieve confident predictions of new compounds not considered in the building of the model. The results of this external validation process show ... -
Subgroup Discovery in MOOCs: A Big Data Application for Describing Different Types of Learners
(Taylor & Francis, 2019)The aim of this paper is to categorize and describe di erent types of learners in mas- sive open online courses (MOOCs) by means of a subgroup discovery approach based on MapReduce. The nal objective is to discover ... -

(Consejo Social de la Universidad de Córdoba, 2012)La iniciativa, cuyo desarrollo ha contado con un presupuesto de 1.000 euros, muestra la transición de la docencia clásica hacia un nuevo método basado en el uso de las herramientas web 2.0, en el que prima que el ... -
Text mining in education
(Wiley, 2019)The explosive growth of online education environments is generating a massive volume of data, specially in text format from forums, chats, social networks, assessments, essays, among others. It produces exciting challenges ... -
Text Mining y Medicina: Una aproximación a la detección temprana de enfermedades
(Universidad de Córdoba, UCOPress, 2020)El futuro próximo de los servicios sanitarios vendrá marcado por el envejecimiento de la población y la cronicidad de las enfermedades. Junto a los cambios demográficos y sociales, se está produciendo un claro aumento de ... -
Técnicas de clasificación para la predicción de tarifas aéreas
(Universidad de Córdoba, UCOPress, 2023)Esta memoria de tesis se enfoca en los problemas multifactoriales a los que se enfrentan las aerolíneas comerciales como son la guerra de precios y la creación de una tabla dinámica de descuentos. Por un lado, dentro de ... -
The AVA Multi-View Dataset for Gait Recognition
(2018)In this paper, we introduce a new multi-view dataset for gait recognition. The dataset was recorded in an indoor scenario, using six convergent cameras setup to produce multi-view videos, where each video depicts a ... -
The use of artificial intelligence for sign language recognition in education: from a literature overview to the ISENSE project
(IEEE, 2023)Common strategies to guarantee the inclusion of d/Deaf students in university are still absent. Recent studies have demonstrated how innovative technologies, such as artificial intelligence and virtual/augmented reality, ... -
Three hypothesis algorithm with occlusion reasoning for multiple people tracking
(IS&T and SPIE, 2015)This work proposes a detection-based tracking algorithm able to locate and keep the identity of multiple people, who may be occluded, in uncontrolled stationary environments. Our algorithm builds a tracking graph that ... -
Time series data mining: preprocessing, analysis, segmentation and prediction. Applications
(Universidad de Córdoba, UCOPress, 2019)Currently, the amount of data which is produced for any information system is increasing exponentially. This motivates the development of automatic techniques to process and mine these data correctly. Specifically, in this ... -
