Entropic and algebraic transcript-based tools in time series analysis
José M. Amigó, Roberto Dale
Algebraic representations of time series are symbolic representations whose symbols belong to a finite group. Precisely, the framework of the present paper is the analysis of coupl…
Permutation-Based Distances for Groups and Group-Valued Time Series
José M. Amigó, Roberto Dale
Permutations on a set, endowed with function composition, build a group called a symmetric group. In addition to their algebraic structure, symmetric groups have two metrics that a…
Generalized synchronization in the presence of dynamical noise and its detection via recurrent neural networks
José M. Amigó, Roberto Dale, Juan C. King +1
Given two unidirectionally coupled nonlinear systems, we speak of generalized synchronization when the responder \textquotedblleft follows\textquotedblright\ the driver. Mathematic…
Violation of Bell inequalities from Cosmic Microwave Background data
Roberto Dale, Jesús M. Gandía, Juan Antonio Morales-Lladosa +1
In a recent paper [R. Dale. R. Lapiedra, and J. A. Morales-Lladosa, Phys. Rev. D {\bf 107}, 023506 (2023)] a cosmic-like Clauser-Horne-Shimony-Holt (CHSH) inequality was proved for…
Blockchain Metrics and Indicators in Cryptocurrency Trading
Juan C. King, Roberto Dale, José M. Amigó
The objective of this paper is the construction of new indicators that can be useful to operate in the cryptocurrency market. These indicators are based on public data obtained fro…
Complexity-based permutation entropies: from deterministic time series to white noise
J. M. Amigó, R. Dale, P. Tempesta
This is a paper in the intersection of time series analysis and complexity theory that presents new results on permutation complexity in general and permutation entropy in particul…
