  • On the stability of generalized second price auctions with budgets 

    Díaz Cort, Josep; Giotis, Ioannis; Kirousis, Lefteris; Markakis, Evangelos; Serna Iglesias, María José (Springer, 2014)
    Conference report
    Open Access
    The Generalized Second Price (GSP) auction used typically to model sponsored search auctions does not include the notion of budget constraints, which is present in practice. Motivated by this, we introduce the different ...
  • Continuous real time POMCP to find-and-follow people by a humanoid service robot 

    Goldhoorn, Alex; Garrell Zulueta, Anais; Alquézar Mancho, René; Sanfeliu Cortés, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 2014)

  • Document-level machine translation with word vector models 

    Martínez Garcia, Eva; España Bonet, Cristina; Márquez Villodre, Luís (2015)
    Conference report
    Open Access
    In this paper we apply distributional semantic information to document-level machine translation. We train monolingual and bilingual word vector models on large corpora and we evaluate them first in a cross-lingual lexical ...
  • Displacement logic for anaphora 

    Morrill, Glyn; Valentín Fernández Gallart, José Oriol (2014-03)
    Article
    Restricted access - publisher's policy
    The displacement calculus of Morrill, Valentín and Fadda (2011) [25] aspires to replace the calculus of Lambek (1958) [13] as the foundation of categorial grammar by accommodating intercalation as well as concatenation ...
  • Reducing the n-gram feature space of class C GPCRs to subtype-discriminating patterns 

    König, Caroline; Alquézar Mancho, René; Vellido Alcacena, Alfredo; Giraldo Arjonilla, Jesús (2014-10-23)
    Article
    Open Access
    G protein-coupled receptors (GPCRs) are a large and heterogeneous superfamily of receptors that are key cell players for their role as extracellular signal transmitters. Class C GPCRs, in particular, are of great interest ...
  • Predicting fecal sources in waters with diverse pollution loads using general and molecular host-specific indicators and applying machine learning methods 

    Casanovas Massana, Arnau; Gómez Doñate, Marta; Sánchez, David; Belanche Muñoz, Luis Antonio; Muniesa, Maite; Blanch, Anicet R. (2015-03-15)
    Article
    Restricted access - publisher's policy
    In this study we use a machine learning software (Ichnaea) to generate predictive models for water samples with different concentrations of fecal contamination (point source, moderate and low). We applied several MST methods ...
  • The placement of the head that minimizes online memory: a complex systems approach 

    Ferrer Cancho, Ramon (2015-03-02)
    Article
    Restricted access - publisher's policy
    It is well known that the length of a syntactic dependency determines its online memory cost. Thus, the problem of the placement of a head and its dependents (complements or modifiers) that minimizes online memory is ...
  • Reply to the commentary "Be careful when assuming the obvious", by P. Alday 

    Ferrer Cancho, Ramon (2015-03-02)
    Article
    Restricted access - publisher's policy
    Here we respond to some comments by Alday concerning headedness in linguistic theory and the validity of the assumptions of a mathematical model for word order. For brevity, we focus only on two assumptions: the unit of ...
  • The ordering principle in a fragment of approximate counting 

    Atserias Peri, Albert; Thapen, Neil (2014)
    Article
    Open Access
    The ordering principle states that every finite linear order has a least element. We show that, in the relativized setting, the surjective weak pigeonhole principle for polynomial time functions does not prove a Herbrandized ...
  • The risks of mixing dependency lengths from sequences of different length 

    Ferrer Cancho, Ramon; Liu, Haitao (2014-11-07)
    Article
    Restricted access - publisher's policy
    Mixing dependency lengths from sequences of different length is a common practice in language research. However, the empirical distribution of dependency lengths of sentences of the same length differs from that of sentences ...
