  • Count-invariance including exponentials 

    Kuznetsov, Stepan; Morrill, Glyn; Valentín, Oriol (Association for Computational Linguistics, 2017)
    Conference lecture
    Restricted access - publisher's policy
    We define infinitary count-invariance for categorial logic, extending countinvariance for multiplicatives (van Benthem, 1991) and additives and bracket modalities (Valentín et al., 2013) to include exponentials. This ...
  • Clustering patients with tensor decomposition 

    Ruffini, Matteo; Gavaldà Mestre, Ricard; Limón, Esther (2017)
    Conference lecture
    Open Access
    In this paper we present a method for the unsupervised clustering of high-dimensional binary data, with a special focus on electronic healthcare records. We present a robust and efficient heuristic to face this problem ...
  • Classifier selection with permutation tests 

    Arias Vicente, Marta; Arratia Quesada, Argimiro Alejandro; Duarte Lopez, Ariel (IOS Press, 2017)
    Conference report
    Open Access
    This work presents a content-based recommender system for machine learning classifier algorithms. Given a new data set, a recommendation of what classifier is likely to perform best is made based on classifier performance ...
  • Parsing logical grammar: CatLog3 

    Morrill, Glyn (Stockholm University, 2017)
    Conference report
    Open Access
    CatLog3 is a Prolog parser/theorem-prover for (type) logical (categorial) grammar. In such logical grammar, grammar is reduced to logic: a string of words is grammatical if and only if an associated logical statement is a ...
  • A polynomial-time algorithm for the Lambek calculus with brackets of bounded order 

    Kanovich, Max; Kuznetsov, Stepan; Morrill, Glyn; Scedrov, Andre (Dagstuhl Publishing, 2017)
    Conference report
    Open Access
    Lambek calculus is a logical foundation of categorial grammar, a linguistic paradigm of grammar as logic and parsing as deduction. Pentus (2010) gave a polynomial-time algorithm for determining provability of bounded depth ...
  • Machine learning assists the classification of reports by citizens on disease-carrying mosquitoes 

    Rodríguez García, Antonio; Bartumeus, Frederic; Gavaldà Mestre, Ricard (CEUR-WS.org, 2016)
    Conference lecture
    Open Access
    Mosquito Alert (www.mosquitoalert.com/en) is an expert-validated citizen science platform for tracking and controlling disease-carrying mosquitoes. Citizens download a free app and use their phones to send reports of ...
  • An alternative to CARMA models via iterations of Ornstein–Uhlenbeck processes 

    Arratia Quesada, Argimiro Alejandro; Cabaña, Ana Alejandra; Cabaña Perez, Enrique (Springer, 2015)
    Conference report
    Restricted access - publisher's policy
    We present a new construction of continuous ARMA processes based on iterating an Ornstein–Uhlenbeck operator OUκ that maps a random variable y(t) onto OUκy(t)=∫t−∞e−κ(t−s)dy(s). This construction resembles the procedure ...
  • Clustering of exchange rates and their dynamics under different dependence measures 

    Renedo, Martí; Arratia Quesada, Argimiro Alejandro (2016)
    Conference report
    Open Access
    This paper proposes an improvement to the method for clustering exchange rates given by D. J. Fenn et al, in Quantitative Finance, 12 (10) 2012, pp.1493-1520. To deal with the potentially non linear nature of currency time ...
  • Material Magic: una proposta per a ludificar l'ensenyament de la ciència de materials a la materia de tecnologia 

    García Pons, Kevin; Hernández Fernández, Antonio (Institut d'Estudis Catalans (IEC), 2016)
    Conference lecture
    Open Access
    En aquest treball s’ha dut a terme una activitat pensada per a secundària en la que s’ha desenvolupat un joc de cartes, Material Magic, com a eina de ludificació per a explicar els continguts i conceptes que es demanen al ...
  • Automated construction and analysis of political networks via open government and media sources 

    García-Olano, Diego; Arias Vicente, Marta; Larriba Pey, Josep (2016)
    Conference report
    Open Access
    We present a tool to generate real world political networks from user provided lists of politicians and news sites. Additional output includes visualizations, interactive tools and maps that allow a user to better understand ...
  • Characterization of order-like dependencies with formal concept analysis 

    Codocedo, Victor; Baixeries i Juvillà, Jaume; Kaytoue, Mehdi; Napoli, Amedeo (2011)
    Conference report
    Open Access
    Functional Dependencies (FDs) play a key role in many fields of the relational database model, one of the most widely used database systems. FDs have also been applied in data analysis, data quality, knowl- edge discovery ...
  • Does training affect match performance? A study using data mining and tracking devices 

    Fernández, Javier; Medina Leal, Daniel; Gómez, Antonio; Arias Vicente, Marta; Gavaldà Mestre, Ricard (2016)
    Conference lecture
    Open Access
    FIFA has recently allowed the use of electronic performance and tracking systems (EPTS) in professional football competition, providing teams with novel and more accurate data. Physical performance has not yet taken much ...
