    Real-time rendering of detailed animated characters in crowd simulations is still a challenging problem in computer graphics. State-of-the-art approaches can render up to several thousand agents by consuming most of the ...
  • Learning probability distributions generated by finite-state machines 

    Castro Rabal, Jorge; Gavaldà Mestre, Ricard (Springer, 2016)
    Capítol de llibre
    Accés restringit per política de l'editorial
    We review methods for inference of probability distributions generated by probabilistic automata and related models for sequence generation. We focus on methods that can be proved to learn in the inference in the limit ...
  • Fast calculation of entropy with Zhang's estimator 

    Lozano Bojados, Antoni; Casas Fernández, Bernardino; Bentz, Chris; Ferrer Cancho, Ramon (RAM - Verlag, 2016-12-01)
    Capítol de llibre
    Accés restringit per política de l'editorial
    Entropy is a fundamental property of a repertoire. Here, we present an efficient algorithm to estimate the entropy of types with the help of Zhang’s estimator. The algorithm takes advantage of the fact that the number of ...

    Convolutional Neural Networks (CNN) are the most popular of deep network models due to their applicability and success in image processing. Although plenty of effort has been made in designing and training better discriminative ...
  • A methodology for maintaining consistency between conceptual interpretations of nested partitions 

    Sevilla-Villanueva, Beatriz; Gibert, Karina; Sànchez-Marrè, Miquel (IOSPress, 2016-10)
    Capítol de llibre
    Accés restringit per política de l'editorial
    The relationship between interpretations of nested partitions is analyzed in this work, since there are multiple situations where a refinement of the original partition arises. As a result, a new methodology NCI-IMS is ...
  • A weighted Cramer's V index for the assessment of stability in the fuzzy clustering of class C G protein-coupled receptors 

    Vellido Alcacena, Alfredo; Halka, Christiana; Nebot Castells, M. Àngela (Springer, 2015)
    Capítol de llibre
    Accés obert
    After decades of intensive use, K-Means is still a common choice for crisp data clustering in real-world applications, particularly in biomedicine and bioinformatics. It is well-known that different initializations of the ...
  • A critical analysis of human-subject experiments in virtual reality and 3D user interfaces 

    Andújar Gran, Carlos Antonio; Brunet Crosa, Pere (Springer International Publishing, 2015)
    Capítol de llibre
    Accés obert
    This paper is about the major peculiarities and difficulties we encounter when trying to validate research results in fields such as virtual reality (VR) and 3D user interfaces (3DUI). We review the steps in the empirical ...
  • Applying 3D graphics for computerized cognitive rehabilitation
