LARCA és un grup de recerca de nivell internacional en temes
d'aprenentatge i mineria de dades, anàlisi de dades i lingüística matemàtica. Típicament, abordem els problemes des de principis matemàtics sòlids, usant eines de modelització i tècniques de l'algorísmia, complexitat computacional, teoria d'autòmats, lògica, matemàtica discreta, estadística, i sistemes dinàmics. Estem iniciant
col·laboracions amb empreses i altres institucions per tal d'aplicar les nostres solucions al problemes del món real.

LARCA is an international research group working on data mining, machine learning, data analysis, and mathematical linguistics. We typically approach problems from sound mathematical principles, using modelling tools and techniques from algorithmics, computational complexity, automata theory, logic, discrete mathematics, statistics, and dynamic systems. We are also starting partnerships with companies and other institutions to apply our solutions to real-world problems.

  • Learning definite Horn formulas from closure queries 

    Arias Vicente, Marta; Balcázar Navarro, José Luis; Tîrnauca, Cristina (2017-01-07)
    Article
    Accés obert
    A definite Horn theory is a set of n-dimensional Boolean vectors whose characteristic function is expressible as a definite Horn formula, that is, as conjunction of definite Horn clauses. The class of definite Horn theories ...
  • Generalising discontinuity 

    Morrill, Glyn; Merenciano Saladrigas, Josep Maria (1996-01)
    Report de recerca
    Accés obert
    This paper makes two generalisations of categorial calculus of discontinuity. In the first we introduce unary modalities which mediate between continuous and discontinuous strings. In the second each of the modes of ...
  • Computational coverage of type logical grammar: The Montague test 

    Morrill, Glyn; Valentín Fernández Gallart, José Oriol (2016)
    Text en actes de congrés
    Accés obert
    It is nearly half a century since Montague made his contributions to the field of logical semantics. In this time, computational linguistics has taken an almost entirely statistical turn and mainstream linguistics has ...
  • Compression and the origins of Zipf's law for word frequencies 

    Ferrer Cancho, Ramon (2016-11-01)
    Article
    Accés obert
    Here we sketch a new derivation of Zipf's law for word frequencies based on optimal coding. The structure of the derivation is reminiscent of Mandelbrot's random typing model but it has multiple advantages over random ...
  • Crossings as a side effect of dependency lengths 

    Ferrer Cancho, Ramon; Gómez Rodríguez, Carlos (2016-11-01)
    Article
    Accés obert
    The syntactic structure of sentences exhibits a striking regularity: dependencies tend to not cross when drawn above the sentence. We investigate two competing explanations. The traditional hypothesis is that this trend ...
  • The infochemical core 

    Hernández Fernández, Antonio; Ferrer Cancho, Ramon (2016-06-07)
    Article
    Accés restringit per política de l'editorial
    Vocalizations, and less often gestures, have been the object of linguistic research for decades. However, the development of a general theory of communication with human language as a particular case requires a clear ...
  • 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 ...
  • Semblant cerca semblant? 

    Sanou Gozalo, Eduard; Arias Vicente, Marta; Ferrer Cancho, Ramon; Hernández Fernández, Antonio (2016)
    Comunicació de congrés
    Accés obert
    En una assignatura del grau d'enginyeria d'informàtica, la pràctica de programació ha passat de ser un treball individual a un treball en equip, en principi per parelles. L'alumnat té llibertat total per formar equips amb ...
  • Contributions to the formalization of order-like dependencies using FCA 

    Codocedo, Victor; Baixeries i Juvillà, Jaume; Kaytoue, Mehdi; Napoli, Amedeo (2016)
    Text en actes de congrés
    Accés obert
    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, knowledge discovery ...
