Co-occurrence patterns in diagnostic data
(Wiley (John Wiley & Sons), 2020-04-12)
Article
Open AccessWe 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
(2020)
Article
Restricted access - publisher's policyThe 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
(2009-04)
Article
Open AccessIt 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
(2019-12-12)
Article
Restricted access - publisher's policyA 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
(2014-12-04)
Article
Open AccessThe 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
(2013-01)
Article
Open AccessThe 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 ... -

Article
Restricted access - publisher's policyA 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
(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 ... -
Linguistic laws in speech: the case of Catalan and Spanish

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 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 ...
