  • Optimization models of natural communication 

    Ferrer Cancho, Ramon (2018-07-03)
    Artículo
    Acceso restringido por política de la editorial
    A family of information theoretic models of communication was introduced more than a decade ago to explain the origins of Zipf’s law for word frequencies. The family is a based on a combination of two information theoretic ...
  • Spurious ambiguity and focalization 

    Morrill, Glyn; Valentín, Oriol (2018-06)
    Artículo
    Acceso abierto
    Spurious ambiguity is the phenomenon whereby distinct derivations in grammar may assign the same structural reading, resulting in redundancy in the parse search space and inefficiency in parsing. Understanding the problem ...
  • Characterizing approximate-matching dependencies in formal concept analysis with pattern structures 

    Baixeries i Juvillà, Jaume; Codocedo, Victor; Kaytoue, Mehdi; Napoli, Amedeo (2018-04-26)
    Artículo

    Functional dependencies (FDs) provide valuable knowledge on the relations between attributes of a data table. A functional dependency holds when the values of an attribute can be determined by another. It has been shown ...
  • A dependency look at the reality of constituency

    A comment on “Neurophysiological dynamics of phrase-structure building during sentence processing” by Nelson et al (2017), Proceedings of the National Academy of Sciences USA 114(18), E3669-E3678.
  • Global optimality in k-means clustering 

    Tîrnauca, Cristina; Gómez Pérez, Domingo; Balcázar Navarro, José Luis; Montaña Arnaiz, José Luis (2018-05-01)
    Artículo

    We study the problem of finding an optimum clustering, a problem known to be NP-hard. Existing literature contains algorithms running in time proportional to the number of points raised to a power that depends on the ...
  • Identifiability and transportability in dynamic causal networks 

    Blondel, Gilles; Arias Vicente, Marta; Gavaldà Mestre, Ricard (Springer, 2017-03)
    Artículo
    Acceso abierto
    In this paper, we propose a causal analog to the purely observational dynamic Bayesian networks, which we call dynamic causal networks. We provide a sound and complete algorithm for the identification of causal effects in ...
  • Thoughts about disordered thinking: measuring and quantifying the laws of order and disorder

  • Adarules: Learning rules for real-time road-traffic prediction 

    Mena Yedra, Rafael; Gavaldà Mestre, Ricard; Casas Vilaró, Jordi (Elsevier, 2017-12-17)
    Texto en actas de congreso
    Acceso abierto
    Traffic management is being more important than ever, especially in overcrowded big cities with over-pollution problems and with new unprecedented mobility changes. In this scenario, road-traffic prediction plays a key ...
  • Does like seek like? The formation of working groups in a programming project 

    Sanou Gozalo, Eduard; Hernández Fernández, Antonio; Arias Vicente, Marta; Ferrer Cancho, Ramon (Omnia Publisher SL (OmniaScience), 2017-02)
    Artículo
    Acceso abierto
    In a course of the degree of computer science, the programming project has changed from individual to teamed work, tentatively in couples (pair programming). Students have full freedom to team up with minimum intervention ...
  • Scarcity of crossing dependencies: A direct outcome of a specific constraint? 

    Gómez Rodríguez, Carlos; Ferrer Cancho, Ramon (American Chemical Society (ACS), 2017-12-04)
    Artículo
    Acceso abierto
    The structure of a sentence can be represented as a network where vertices are words and edges indicate syntactic dependencies. Interestingly, crossing syntactic dependencies have been observed to be infrequent in human ...
  • Are crossing dependencies really scarce? 

    Ferrer Cancho, Ramon; Gómez Rodríguez, Carlos; Esteban Ángeles, Juan Luis (2018-03-01)
    Artículo
    Acceso restringido por política de la editorial
    The syntactic structure of a sentence can be modelled as a tree, where vertices correspond to words and edges indicate syntactic dependencies. It has been claimed recurrently that the number of edge crossings in real ...
