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. [...]

See Stankoff and Louapre (doi:) for a scientific commentary on this article. Grey matter atrophy in multiple sclerosis affects certain areas preferentially. Eshaghi et al. use a data-driven computational model to predict the order in which regions atrophy, and use this sequence to stage patients. [...]

Departament de Telecomunicació i Enginyeria de Sistemes) ; De la Sen, Manuel (Universidad del País Vasco. Instituto de Investigación y Desarrollo de Procesos)
In this paper, we introduce the concept of enhanced probabilistic metric space (briefly EPM-space) as a type of probabilistic metric space. Also, we investigate the existence of fixed points for a (finite or infinite) linear combination of different types of contractive mappings in EPM-spaces. [...]

50 p, 1.3 MB What sort of cognitive hypothesis is a derivational theory of grammar? / Hunter, Tim (University of California)
This paper has two closely related aims. The main aim is to lay out one specific way in which the derivational aspects of a grammatical theory can contribute to the cognitive claims made by that theory, to demonstrate that it is not only a theory's posited representations that testable cognitive hypotheses derive from. [...]
Aquest article té dos objectius estretament relacionats. L'objectiu principal és exposar una forma específica en la qual els aspectes derivatius d'una teoria gramatical poden contribuir a les afirmacions cognitives realitzades per aquesta teoria, per demostrar que no són només les representacions plantejades d'una teoria de les que es deriven hipòtesis cognitives testables.

21 p, 1.4 MB Probabilistic metrology or how some measurement outcomes render ultra-precise estimates / Calsamiglia Costa, John (Universitat Autònoma de Barcelona. Departament de Física) ; Gendra Casalí, Bernat (Universitat Autònoma de Barcelona. Departament de Física) ; Muñoz Tapia, Ramon (Universitat Autònoma de Barcelona. Departament de Física) ; Bagán Capella, Emili (Universitat Autònoma de Barcelona. Departament de Física)
We show on theoretical grounds that, even in the presence of noise, probabilistic measurement strategies (which have a certain probability of failure or abstention) can provide, upon a heralded successful outcome, estimates with a precision that exceeds the deterministic bounds for the average precision.

27 p, 2.5 MB On fixed points and convergence results of sequences generated by uniformly convergent and point-wisely convergent sequences of operators in Menger probabilistic metric spaces / De la Sen, Manuel (Institute of Research and Development of Processes IIDP, Faculty of Science and Technology, University of the Basque Country, PO Box 644, de Bilbao, Barrio Sarriena, 48940 Leioa, Bizkaia Spain) ; Ibeas, Asier (Universitat Autònoma de Barcelona.

In the framework of complete probabilistic Menger metric spaces, this paper investigates some relevant properties of convergence of sequences built through sequences of operators which are either uniformly convergent to a strict k -contractive operator, for some real constant k ∈ (0, 1), or which are strictly k -contractive and point-wisely convergent to a limit operator.

Las fuentes históricas de naturaleza demográfica permiten estudiar no solo el comportamiento demográfico, si no también entender la evolución social y económica del pasado. Para que toda esta información sea útil en investigaciones, es necesario realizar una vinculación de estos datos, pero a la hora de realizar vinculaciones de censos y padrones históricos existen varias dificultades.
