Non-sequential recursive pair substitutions and numerical entropy estimates in symbolic dynamical systems
Lucio M. Calcagnile, Stefano Galatolo, Giulia Menconi
We numerically test the method of non-sequential recursive pair substitutions to estimate the entropy of an ergodic source. We compare its performance with other classical methods…
Data compression and genomes: a two dimensional life domain map
Giulia Menconi, Vieri Benci, Marcello Buiatti
We define the complexity of DNA sequences as the information content per nucleotide, calculated by means of some Lempel-Ziv data compression algorithm. It is possible to use the st…
Multi-dimensional sparse time series: feature extraction
Marco Franciosi, Giulia Menconi
We show an analysis of multi-dimensional time series via entropy and statistical linguistic techniques. We define three markers encoding the behavior of the series, after it has be…
Phase transitions in social sciences: two-populations mean field theory
Pierluigi Contucci, Ignacio Gallo, Giulia Menconi
A new mean field statistical mechanics model of two interacting groups of spins is introduced and the phase transition studied in terms of their relative size. A jump of the averag…
Sublinear Growth of Information in DNA Sequences
Giulia Menconi
We introduce a novel method to analyse complete genomes and recognise some distinctive features by means of an adaptive compression algorithm, which is not DNA-oriented. We study t…
Vortex dynamics in evolutive flows: a weakly chaotic phenomenon
Jacopo Bellazzini, Giulia Menconi, Guido Buresti +2
We study the vortex dynamics in an evolutive flow. We carry out the statistical analysis of the resulting time series by means of the joint use of a compression and an entropy diff…
