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.

  • An alternative to CARMA models via iterations of Ornstein–Uhlenbeck processes 

    Arratia Quesada, Argimiro Alejandro; Cabaña, Ana Alejandra; Cabaña Perez, Enrique (Springer, 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    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 ...
  • Positive isometric averaging operators on l2(Z,µ) 

    Boza Rocho, Santiago; Soria de Diego, Javier (2016-03-05)
    Article
    Accés restringit per política de l'editorial
    © 2016 Springer International Publishing We show that positive isometric averaging operators on the sequence space (Formula presented.) are determined by very subtle arithmetic conditions on (Formula presented.) (even for ...
  • Nonuniform complexity classes specified by lower and upper bounds 

    Balcázar Navarro, José Luis; Gabarró Vallès, Joaquim (1989-09)
    Article
    Accés obert
    We characterize in terms of oracle Turing machines the classes defined by exponential lower bounds on some nonuniform complexity measures. After, we use the same methods to giue a new characterization of classes defined ...

    En el presente artículo se revisan sucintamente las posibilidades y capacidades educativas de la ciencia ficción en los libros de texto, y se presentan ejemplos de cómo plantear la ciencia ficción en actividades introductorias ...
  • Clustering of exchange rates and their dynamics under different dependence measures 

    Renedo, Martí; Arratia Quesada, Argimiro Alejandro (, 2016)
    Text en actes de congrés
    Accés obert
    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 ...
  • Immunity and simplicity in relativizations of probabilistic complexity classes 

    Balcázar Navarro, José Luis; Russo, David A. (1988-05)
    Article
    Accés obert
    The existence of immune and simple sets in relativizations of the probabilistic polynomial time bounded classes is studied. Some techniques previously used to show similar results for relativizations of P and NP are adapted ...

    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 ...
  • Sparse sets, lowness, and highness 

    Balcázar Navarro, José Luis; Book, R; Schoening, U (1986-08)
    Article
    Accés obert
    We develop the notions of “generalized lowness” for sets in PH (the union of the polynomial-time hierarchy) and of “generalized highness” for arbitrary sets. Also, we develop the notions of “extended lowness” and “extended ...
  • Acoustic sequences in non-human animals: a tutorial review and prospectus
