Approximate entropy as a measure of system complexity.
Techniques to determine changing system complexity from data are evaluated. Convergence of a frequently used correlation dimension algorithm to a finite value does not necessarily imply an underlying deterministic model or chaos. Analysis of a recently developed family of formulas and statistics, approximate entropy (ApEn), suggests that ApEn can classify complex systems, given at least 1000 da...
متن کاملMultiscale Cross-Approximate Entropy Analysis as a Measure of Complexity among the Aged and Diabetic
Complex fluctuations within physiological signals can be used to evaluate the health of the human body. This study recruited four groups of subjects: young healthy subjects (Group 1, n = 32), healthy upper middle-aged subjects (Group 2, n = 36), subjects with well-controlled type 2 diabetes (Group 3, n = 31), and subjects with poorly controlled type 2 diabetes (Group 4, n = 24). Data acquisitio...
متن کاملApproximate Entropy as a Measure of Regularity in Hormone Series
1. Introduction Hormones, such as luteinizing hormone (LH), are secreted into the blood in short bursts, called pulses, and removed by a decay process. Using hormone assays from blood samples obtained at equally spaced intervals, investigators study secretion characteristics such as pulse frequency and amplitude to learn whether various diseases affect hormone secretion. Approximate entropy (Ap...
متن کاملIncrement Entropy as a Measure of Complexity for Time Series
Entropy has been a common index to quantify the complexity of time series in a variety of fields. Here, we introduce an increment entropy to measure the complexity of time series in which each increment is mapped onto a word of two letters, one corresponding to the sign and the other corresponding to the magnitude. Increment entropy (IncrEn) is defined as the Shannon entropy of the words. Simul...
متن کاملWavelet entropy as a measure of solar cycle complexity
Using wavelet analysis approach, we can derive a measure of the disorder content of solar activity, following the temporal evolution of the so-called wavelet entropy. The interesting feature of this parameter is its ability to extract a dynamical complexity information, in terms of frequency distribution of the energy content, avoiding restrictions, common in the nonlinear dynamics theory, such...
