    La implantación de los títulos de Grado y Postgrado propuestos en el EEES supone el rediseño de los planes de estudios de todas las universidades europeas. De la estrategia de desarrollo utilizada para su diseño dependerá ...
  • Co-occurrence patterns in diagnostic data 

    Piceno Cabrera, Marie Ely; Rodríguez Navas, Laura; Balcázar Navarro, José Luis (Wiley (John Wiley & Sons), 2020-04-12)
    Article
    Open Access
    We demonstrate how graph decomposition techniques can be employed for the visualization of hierarchical co-occurrence patterns between medical data items. Our research is based on Gaifman graphs (a mathematical concept ...
  • Closed-set-based discovery of representative association rules 

    Tîrnauca, Cristina; Balcázar Navarro, José Luis; Gómez Pérez, Domingo (2020)
    Article
    Restricted access - publisher's policy
    The output of an association rule miner is often huge in practice. This is why several concise lossless representations have been proposed, such as the “essential” or “representative” rules. A previously known algorithm ...
  • The frequency spectrum of finite samples from the intermittent silence process 

    Ferrer Cancho, Ramon; Gavaldà Mestre, Ricard (2009-04)
    Article
    Open Access
    It has been argued that the actual distribution of word frequencies could be reproduced or explained by generating a random sequence of letters and spaces according to the so-called intermittent silence process. The same ...
  • Portfolio optimization in incomplete markets and price constraints determined by maximum entropy in the mean 

    Arratia Quesada, Argimiro Alejandro; Gzyl, Henryk (2019-12-12)
    Article
    Restricted access - publisher's policy
    A solution to a portfolio optimization problem is always conditioned by constraints on the initial capital and the price of the available market assets. If a risk neutral measure is known, then the price of each asset is ...
  • A stronger null hypothesis for crossing dependencies 

    Ferrer Cancho, Ramon (2014-12-04)
    Article
    Open Access
    The syntactic structure of a sentence can be modeled as a tree where vertices are words and edges indicate syntactic dependencies between words. It is well known that those edges normally do not cross when drawn over the ...
  • The challenges of statistical patterns of language: the case of Menzerath's law in genomes 

    Ferrer Cancho, Ramon; Forns Fradera, Núria; Hernández Fernández, Antonio; Bel Enguix, Gemma; Baixeries i Juvillà, Jaume (2013-01)
    Article
    Open Access
    The importance of statistical patterns of language has been debated over decades. Although Zipf's law is perhaps the most popular case, recently, Menzerath's law has begun to be involved. Menzerath's law manifests in ...
  • ¿Es el habla una señal crítica auto-organizada? 

    González Torre, Iván; Artime, Oriol; Hernández Fernández, Antonio; Luque Serrano, Bartolome (Universidad Nacional Autónoma de México, 2020-01-01)
    Article
    Restricted access - publisher's policy
    A lo largo del siglo XX, los estudios en lingüística cuantitativa han ido mostrando la aparición de leyes potenciales en las lenguas, primero en textos escritos y posteriormente en el habla. Son leyes que parecen ubicuas ...
  • On the physical origin of linguistic laws and lognormality in speech 

    González Torre, Iván; Luque Serrano, Bartolome; Lacasa, Lucas; Kello, Christopher; Hernández Fernández, Antonio (2019-08-21)
    Article
    Open Access
    Physical manifestations of linguistic units include sources of variability due to factors of speech production which are by definition excluded from counts of linguistic symbols. In this work, we examine whether linguistic ...
  • Linguistic laws in speech: the case of Catalan and Spanish 

    Hernández Fernández, Antonio; González Torre, Iván; Garrido, Juan Maria; Lacasa, Lucas (2019-11-26)
    Article
    Open Access
    In this work we consider Glissando Corpus—an oral corpus of Catalan and Spanish—and empirically analyze the presence of the four classical linguistic laws (Zipf’s law, Herdan’s law, Brevity law, and Menzerath–Altmann’s ...
  • On the efficacy of stop-loss rules in the presence of overnight gaps 

    Arratia Quesada, Argimiro Alejandro; Dorador Chalar, Albert (2019-04-30)
    Article
    Restricted access - publisher's policy
    A stop-loss rule is a risk management tool whereby the investor predefines some condition that, upon being triggered by market dynamics, implies the liquidation of her outstanding position. Such a tool is widely used by ...
  • Anti dependency distance minimization in short sequences: A graph theoretic approach 

    Ferrer Cancho, Ramon; Gómez Rodríguez, Carlos (Informa UK (Taylor & Francis), 2019-08-22)
    Article
    Restricted access - publisher's policy
    Dependency distance minimization (DDm) is a word order principle favouring the placement of syntactically related words close to each other in sentences. Massive evidence of the principle has been reported for more than a ...
