  • A commentary on “The now-or-never bottleneck: a fundamental constraint on language”, by Christiansen and Chater (2016) 

    Ferrer Cancho, Ramon (RAM-Verlag, 2017-07-02)
    Article
    Accés obert
    In a recent article, Christiansen and Chater (2016) present a fundamental constraint on language, i.e. a now-or-never bottleneck that arises from our fleeting memory, and explore its implications, e.g., chunk-and-pass ...
  • A correction on Shiloach's algorithm for minimum linear arrangement of trees 

    Esteban Ángeles, Juan Luis; Ferrer Cancho, Ramon (2017-06-29)
    Article
    Accés obert
    More than 30 years ago, Shiloach published an algorithm to solve the minimum linear arrangement problem for undirected trees. Here we fix a small error in the original version of the algorithm and discuss its effect on ...

    Kershenbaum, Arik; Blumstein, Daniel T.; Roch, Marie A.; Ferrer Cancho, Ramon (2016-02)
    Article
    Accés obert
    Animal acoustic communication often takes the form of complex sequences, made up of multiple distinct acoustic units. Apart from the well-known example of birdsong, other animals such as insects, amphibians, and mammals ...

  • A law of word meaning in dolphin whistle types 

    Ferrer Cancho, Ramon; McCowan, Brenda (2009-10-30)
    Article
    Accés obert
    We show that dolphin whistle types tend to be used in specific behavioral contexts, which is consistent with the hypothesis that dolphin whistle have some sort of “meaning”. Besides, in some cases, it can be shown that the ...
  • Are crossing dependencies really scarce? 

    Ferrer Cancho, Ramon; Gómez Rodríguez, Carlos; Esteban Ángeles, Juan Luis (2018-03-01)
    Article
    Accés restringit per política de l'editorial
    The syntactic structure of a sentence can be modelled as a tree, where vertices correspond to words and edges indicate syntactic dependencies. It has been claimed recurrently that the number of edge crossings in real ...
  • Beyond description: Comment on “Approaching human language with complex networks” by Cong and Liu 

    Ferrer Cancho, Ramon (2014-12-01)

  • 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 ...
  • Compression as a universal principle of animal behavior 

    Ferrer Cancho, Ramon; Hernández Fernández, Antonio; Lusseau, David; Agoramoorthy, Govindasamy; Hsu, Minna J.; Semple, Stuart (2013)
    Article
    Accés restringit per política de l'editorial
    A key aim in biology and psychology is to identify fundamental principles underpinning the behavior of animals, including humans. Analyses of human language and the behavior of a range of non-human animal species have ...
  • 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 ...
  • Does like seek like? The formation of working groups in a programming project 

    Sanou Gozalo, Eduard; Hernández Fernández, Antonio; Arias Vicente, Marta; Ferrer Cancho, Ramon (Omnia Publisher SL (OmniaScience), 2017-02)
    Article
    Accés obert
    In a course of the degree of computer science, the programming project has changed from individual to teamed work, tentatively in couples (pair programming). Students have full freedom to team up with minimum intervention ...
  • El bajo rendimiento teórico de los alumnos en asignaturas teórico-prácticas: posibles soluciones 

    Ferrer Cancho, Ramon; Arias Vicente, Marta (2010)
    Comunicació de congrés
    Accés obert
    En este trabajo analizamos el rendimiento de los alumnos a lo largo de tres cuatrimestres en la asignatura compiladores de la ingeniería informática. Esta asignatura combina conocimientos teóricos sobre compilación con el ...

    Comunicació de congrés
    Accés obert
    La asignatura de Introducción a la Lógica es una asignatura del primer año de Ingeniería en Informática impartida en la Facultad de Informática de Barcelona (UPC). La asignatura fue rediseñada en el curso 06-07 y pasó a ...
  • 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 ...
  • Gelada vocal sequences follow Menzerath's linguistic law 

    Gustison, Morgan; Semple, Stuart; Ferrer Cancho, Ramon; Bergman, Thore (2016-03-04)
    Article
    Accés obert
    Identifying universal principles underpinning diverse natural systems is a key goal of the life sciences. A powerful approach in addressing this goal has been to test whether patterns consistent with linguistic laws are ...
  • Kauffman's adjacent possible in word order evolution 

    Ferrer Cancho, Ramon (2016)
    Text en actes de congrés
    Accés obert
    Word order evolution has been hypothesized to be constrained by a word order permutation ring: transitions involving orders that are closer in the permutation ring are more likely. The hypothesis can be seen as a particular ...

    Ferrer Cancho, Ramon; Gómez Rodríguez, Carlos (2016-02-25)
    Article

  • Non-crossing dependencies: Least effort, not grammar 

    Ferrer Cancho, Ramon (Springer, 2016-01-01)
    Capítol de llibre
    Accés obert
    The use of null hypotheses (in a statistical sense) is common in hard sciences but not in theoretical linguistics. Here the null hypothesis that the low frequency of syntactic dependency crossings is expected by an arbitrary ...
  • Optimization models of natural communication

    Article
    Accés restringit per política de l'editorial
    A family of information theoretic models of communication was introduced more than a decade ago to explain the origins of Zipf’s law for word frequencies. The family is a based on a combination of two information theoretic ...
