Linguistic laws in speech: the case of Catalan and Spanish
(2019-11-26)
Article
Open AccessIn 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 physical origin of linguistic laws and lognormality in speech
(2019-08-21)
Article
Open AccessPhysical 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 ... -
On the efficacy of stop-loss rules in the presence of overnight gaps
(2019-04-30)
Article
Restricted access - publisher's policyA 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
(Informa UK (Taylor & Francis), 2019-08-22)
Article
Restricted access - publisher's policyDependency 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 ... -
Polysemy and brevity versus frequency in language
(Elsevier, 2019-11-01)
Article
Open AccessThe pioneering research of G. K. Zipf on the relationship between word frequency and other word features led to the formulation of various linguistic laws. The most popular is Zipf’s law for word frequencies. Here we focus ... -
The sum of edge lengths in random linear arrangements
(Institute of Physics (IOP), 2019-05-09)
Article
Restricted access - publisher's policySpatial networks are networks where nodes are located in a space equipped with a metric. Typically, the space is two-dimensional and until recently and traditionally, the metric that was usually considered was the Euclidean ... -
Relative entailment among probabilistic implications
(2019-02-06)
Article
Open AccessWe study a natural variant of the implicational fragment of propositional logic. Its formulas are pairs of conjunctions of positive literals, related together by an implicational-like connective; the semantics of this sort ... -
Weighted contrastive divergence
(2019-06)
Article
Restricted access - publisher's policyLearning algorithms for energy based Boltzmann architectures that rely on gradient descent are in general computationally prohibitive, typically due to the exponential number of terms involved in computing the partition ... -
American and exotic options in a market with frictions
(2019-04-01)
Article
Restricted access - publisher's policyIn a market with frictions, bid and ask prices are described by sublinear pricing functionals, which can be defined recursively using coherent risk measures. We prove the convergence of bid and ask prices for various ... -
Averaging operators on decreasing or positive functions: equivalence and optimal bounds
(Elsevier, 2019-01-01)
Article
Restricted access - publisher's policyWe study the optimal bounds for the Hardy operator S minus the identity, as well as S and its dualoperator S*, on the full range 1 = p = 8, for the cases of decreasing, positive or general functions (infact, these two kinds ... -
Linguistic laws in chimpanzee gestural communication
(2019-02-13)
Article
Open AccessStudies testing linguistic laws outside language have provided important insights into the organization of biological systems. For example, patterns consistent with Zipf's law of abbreviation (which predicts a negative ... -
The polysemy of the words that children learn over time
(2018-12)
Article
Open AccessHere we study polysemy as a potential learning bias in vocabulary learning in children. We employ a massive set of transcriptions of conversations between children and adults in English, to analyze the evolution of mean ...
