Unsupervised Symbolization of Signal Time Series for Extraction of the Embedded Information
Entropy, 2017 This paper formulates an unsupervised algorithm for symbolization of signal time series to capture the embedded dynamic behavior. The key idea is to convert time series of the digital signal into a string of (spatially discrete) symbols from which the ...

On the Entropy of a Two Step Random Fibonacci Substitution
Entropy, 2013 We consider a random generalization of the classical Fibonacci substitution. The substitution we consider is defined as the rule mapping, a → baa and b → ab, with probability , and → ba, with probability 1 – p for 0 < p < 1, and where the random rule is

Subshifts on Infinite Alphabets and Their Entropy
Entropy, 2020 We analyze symbolic dynamics to infinite alphabets by endowing the alphabet with the cofinite topology. The topological entropy is shown to be equal to the supremum of the growth rate of the complexity function with respect to finite subalphabets.

Orbit Representations from Linear mod 1 Transformations
Symmetry, Integrability and Geometry: Methods and Applications, 2012 We show that every point $x_0in [0,1]$ carries a representationof a $C^*$-algebra that encodes the orbit structure of thelinear mod 1 interval map $f_{eta,alpha}(x)=eta x +alpha$.

A symbolic projection of Langton's Ant [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 The Langton's ant is studied from the point of view of topological dynamical systems. A new approach which associate a subshift to the system is proposed.The transition rule is generalized to the family of bi-regular graphs $\Gamma(k,d)$ and the ...
