12 p, 537.4 KB The space of models in machine learning : using Markov chains to model transitions / Torra, Vicenç (Umeå University. Department Computing Science) ; Taha, Mariam (Umeå University. Department Computing Science) ; Navarro-Arribas, Guillermo (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions)
Machine and statistical learning is about constructing models from data. Data is usually understood as a set of records, a database. Nevertheless, databases are not static but change over time. We can understand this as follows: there is a space of possible databases and a database during its lifetime transits this space. [...]

18 p, 391.1 KB Estadística por proyectos en el grado de Educación Primaria : un estudio de casos / Anasagasti Aguirre, Jon (Universidad del País Vasco) ; Berciano Alcaraz, Ainhoa (Universidad del País Vasco) ; Murillo Ramón, Jesús (Universidad de La Rioja)
Entre los principios metodológicos apropiados para la enseñanza-aprendizaje de la estadística destaca el aprendizaje basado en proyectos (ABP). En este artículo centramos nuestro interés en identificar las características emergentes de la implementación de un módulo diseñado según los principios metodológicos del ABP. [...]
Among the appropriate methodological principles for the teaching-learning of statistics, project-based learning (PBL) stands out. In this article, we focus on identifying the emerging characteristics of the implementation of a module designed according to the methodological principles of PBL. [...]

20 p, 395.8 KB Joint outlier detection and variable selection using discrete optimization / Jammal, Mahdi ; Canu, Stephane ; Abdallah, Maher
In regression, the quality of estimators is known to be very sensitive to the presence of spurious variables and outliers. Unfortunately, this is a frequent situation when dealing with real data. To handle outlier proneness and achieve variable selection, we propose a robust method performing the outright rejection of discordant observations together with the selection of relevant variables. [...]

16 p, 1.5 MB Inferring locomotor behaviours in Miocene New World monkeys using finite element analysis, geometric morphometrics and machine-learning classification techniques applied to talar morphology / Püschel, Thomas (University of Manchester. School of Earth and Environmental Sciences) ; Marcé Nogué, Jordi (Institut Català de Paleontologia Miquel Crusafont) ; Gladman, Justin T. (Duke University. Department of Engineering, Shared Materials Instrumentation Facility) ; Bobe, René (University of Oxford. Institute of Cognitive and Evolutionary Anthropology) ; Sellers, William I. (University of Manchester. School of Earth and Environmental Sciences)
The talus is one of the most commonly preserved post-cranial elements in the platyrrhine fossil record. Talar morphology can provide information about postural adaptations because it is the anatomical structure responsible for transmitting body mass forces from the leg to the foot. [...]

24 p, 294.5 KB A statistical learning based approach for parameter fine-tuning of metaheuristics / Calvet Liñan, Laura (Universitat Oberta de Catalunya) ; Juan, Ángel A., dir. (Universitat Autònoma de Barcelona. Departament de Telecomunicació i Enginyeria de Sistemes) ; Serrat, Carles (Universitat Politècnica de Catalunya. Departament de Matemàtica Aplicada I) ; Ries, Jana (University of Portsmouth. Portsmouth Business School)
Metaheuristics are approximation methods used to solve combinatorial optimization problems. Their performance usually depends on a set of parameters that need to be adjusted. The selectionof appropriate parameter values causes a loss of efficiency, as it requires time, and advanced analytical and problem-specific skills. [...]

3 p, 25.1 KB Adaptive texture description and estimation of the class prior probabilities for seminal quality control / González-Castro, Víctor
Semen quality assessment is a crucial task in artificial insemination processes, both for humans and animals. Animal artificial insemination allows farmers to save time and money (e. g. working with a limited number of animals). [...]

2 p, 5.0 MB Semantic Awareness for Automatic Image Interpretation / Lindner, Albrecht
Finding relations between image semantics and image characteristics is a problem of long standing in computer vision, image analysis or related fields. Classic research in these fields is intended for applications that go from the image domain to the semantic domain such as face recognition or scene understanding. [...]
