  • Stopping criteria in contrastive divergence: Alternatives to the reconstruction error 

    Buchaca, David; Romero Merino, Enrique; Mazzanti Castrillejo, Fernando Pablo; Delgado Pin, Jordi (2014)
    Conference report
    Open Access
    Restricted Boltzmann Machines (RBMs) are general unsupervised learning devices to ascertain generative models of data distributions. RBMs are often trained using the Contrastive Divergence learning algorithm (CD), an ...
  • An agent-based model studying the acquisition of a language system of logical constructions 

    Sierra Santibáñez, Josefina (AAAI Press. Association for the Advancement of Artificial Intelligence, 2014)
    Conference report
    Open Access
    This paper presents an agent-based model that studies the emergence and evolution of a language system of logical constructions, i.e. a vocabulary and a set of grammatical constructions that allows the expression of logical ...
  • A multi-agent experiment on the acquisition of a language system of logical constructions 

    Sierra Santibáñez, Josefina (CEUR Workshop Proceedings, 2014)
    Conference report
    Open Access
    This paper analyses an experiment which studies the acquisition of the linguistic competence required to communicate logical combinations of categories from the wisdom of the crowds perspective. The acquisition of such ...

  • Unsupervised spectral learning of FSTs 

    Bailly, Raphaël; Carreras Pérez, Xavier; Quattoni, Ariadna Julieta (2013)
    Conference report
    Open Access
    Finite-State Transducers (FST) are a standard tool for modeling paired input output sequences and are used in numerous applications, ranging from computational biology to natural language processing. Recently Balle et al. ...
  • Why might SOV be initially preferred and then lost or recovered? A theoretical framework 

    Ferrer Cancho, Ramon (World Scientific, 2014)
    Conference report
    Open Access
    Little is known about why SOV order is initially preferred and then discarded or recovered. Here we present a framework for understanding these and many related word order phenomena: the diversity of dominant orders, the ...
  • Power-aware multi-data center management using machine learning 

    Berral García, Josep Lluís; Gavaldà Mestre, Ricard; Torres Viñals, Jordi (2013)
    Conference report
    Open Access
    The cloud relies upon multi-datacenter (multi-DC) infrastructures distributed along the world, where people and enterprises pay for resources to offer their web-services to worldwide clients. Intelligent management is ...
  • The evolution of polysemy in child language 

    Casas Fernández, Bernardino; Catala Roig, Neus; Ferrer Cancho, Ramon; Baixeries i Juvillà, Jaume (World Scientific Publishing Company, 2014)
    Conference report
    Open Access
    It has been hypothesized that early stages of language have left traces of simpler forms of language, for instance, in child language (Bickerton, 1990; Jackendoff, 1999). Word learning biases in children (Saxton, 2010) ...
