  • The polysemy of the words that children learn over time 

    Casas Fernández, Bernardino; Catala Roig, Neus; Ferrer Cancho, Ramon; Hernández Fernández, Antonio; Baixeries i Juvillà, Jaume (2018-12)
    Article
    Accés obert
    Here we study polysemy as a potential learning bias in vocabulary learning in children. We employ a massive set of transcriptions of conversations between children and adults in English, to analyze the evolution of mean ...
  • Multiview: a software package for multiview pattern recognition methods 

    Kanaan Izquierdo, Samir; Ziyatdinov, Andrey; Burgueño, Maria Araceli; Perera Lluna, Alexandre (2018-12-31)
    Article
    Accés obert
    Multiview datasets are the norm in bioinformatics, often under the label multi-omics. Multiview data is gathered from several experiments, measurements or feature sets available for the same subjects. Recent studies in ...
  • A note on movement in logical grammar 

    Morrill, Glyn (2018)
    Article
    Accés obert
    In this article, we make some brief remarks on overt and covert movement in logical grammar. With respect to covert movement (e.g. quantification), we observe how a treatment in terms of displacement calculus interacts ...
  • Top-down model fitting for hand pose recovery in sequences of depth images 

    Madadi, Meysam; Escalera, Sergio; Carruesco Llorens, Àlex; Andújar Gran, Carlos Antonio; Baró, Xavier; Gonzàlez, Jordi (2018-11)
    Article
    Accés restringit per política de l'editorial
    State-of-the-art approaches on hand pose estimation from depth images have reported promising results under quite controlled considerations. In this paper we propose a two-step pipeline for recovering the hand pose from a ...
  • A Tabu search algorithm for scheduling independent jobs in computational grids 

    Xhafa Xhafa, Fatos; Carretero Casado, Javier Sebastián; Dorronsoro, Bernabé; Alba, Enrique (2009)
    Article
    Accés obert
    The efficient allocation of jobs to grid resources is indispensable for high performance grid-based applications, and it is a computationally hard problem even when there are no dependencies among jobs. We present in this ...
  • Using contextual information in music playlist recommendations 

    Gatzioura, Ana; Sànchez-Marrè, Miquel (IOS Press, 2017-10-01)
    Article
    Accés obert
    Recommender Systems have become a fundamental part of various applications supporting users when searching for items they could be interested in, at a given moment. However, the majority of Recommender Systems generate ...
  • Generating complete menus from nutritional prescriptions by using advanced CBR and Real Food Databases 

    Sevilla-Villanueva, Beatriz; Gibert, Karina; Sànchez-Marrè, Miquel (IOS Press, 2017-10-01)
    Article
    Accés restringit per política de l'editorial
    Prevention and nutrition are key issues to guarantee a healthy lifestyle and are in the kernel of the new paradigm of patient-centered medicine. A healthy diet protects against risk factors of a large number of chronic ...
  • A simulated annealing algorithm for router nodes placement problem in Wireless Mesh Networks 

    Xhafa Xhafa, Fatos; Barolli, Admir; Sánchez Lopez, Christian; Barolli, Leonard (2011-11)
    Article
    Accés obert
    Mesh router nodes placement is a central problem in Wireless Mesh Networks (WMNs). An efficient placement of mesh router nodes is indispensable for achieving network performance in terms of both network connectivity and ...
  • Enhancing knowledge management in online collaborative learning 

    Caballé Llobet, Santiago; Daradoumis, Thanasis; Xhafa Xhafa, Fatos; Conesa Caralt, Jordi (2010-06)
    Article
    Accés obert
    This paper aims to explore two crucial aspects of collaborative work and learning: on the one hand, the importance of enabling collaborative learning applications to capture and structure the information generated by group ...
  • A hyper-heuristic for adaptive scheduling in computational grids 

    Xhafa Xhafa, Fatos (2007-01)
    Article
    Accés obert
    In this paper we present the design and implementation of an hyper-heuristic for efficiently scheduling independent jobs in computational grids. An efficient scheduling of jobs to grid resources depends on many parameters, ...
  • Proof complexity meets algebra 

    Atserias, Albert; Ochremiak, Joanna (2018-12-01)
    Article
    Accés obert
    We analyze how the standard reductions between constraint satisfaction problems affect their proof complexity. We show that, for the most studied propositional, algebraic, and semialgebraic proof systems, the classical ...
  • Translation of neutrally evolving peptides provides a basis for de novo gene evolution 

    Ruiz Orera, Jorge; Verdaguer Grau, Pol; Villanueva Cañas, José Luis; Messeguer Peypoch, Xavier; Albà Soler, M. Mar (Springer, 2018-03-19)
    Article
    Accés obert
    Accumulating evidence indicates that some protein-coding genes have originated de novo from previously non-coding genomic sequences. However, the processes underlying de novo gene birth are still enigmatic. In particular, ...
