Approximate Entropy and Sample Entropy: A Comprehensive Tutorial [PDF]

open access: yesEntropy, 2019
Approximate Entropy and Sample Entropy are two algorithms for determining the regularity of series of data based on the existence of patterns. Despite their similarities, the theoretical ideas behind those techniques are different but usually ignored ...

Approximate Entropy in Canonical and Non-Canonical Fiction [PDF]

open access: yesEntropy, 2022
Computational textual aesthetics aims at studying observable differences between aesthetic categories of text. We use Approximate Entropy to measure the (un)predictability in two aesthetic text categories, i.e., canonical fiction (‘classics’) and non ...

New Fast ApEn and SampEn Entropy Algorithms Implementation and Their Application to Supercomputer Power Consumption [PDF]

open access: yesEntropy, 2020
Approximate Entropy and especially Sample Entropy are recently frequently used algorithms for calculating the measure of complexity of a time series. A lesser known fact is that there are also accelerated modifications of these two algorithms, namely ...

Dynamic approximate entropy electroanatomic maps detect rotors in a simulated atrial fibrillation model. [PDF]

open access: yesPLoS ONE, 2014
There is evidence that rotors could be drivers that maintain atrial fibrillation. Complex fractionated atrial electrograms have been located in rotor tip areas.

Evaluation of Bubble Entropy Using Heart Rate Variability [PDF]

open access: yesEntropy
Bubble entropy has established its own place in the research community, representing a new and promising definition of entropy. Based on the work required to order a vector in an embedding space of dimension m, Bubble entropy gives a physical ...

Combination of R-R Interval and Crest Time in Assessing Complexity Using Multiscale Cross-Approximate Entropy in Normal and Diabetic Subjects [PDF]

open access: yesEntropy, 2018
The present study aimed at testing the hypothesis that application of multiscale cross-approximate entropy (MCAE) analysis in the study of nonlinear coupling behavior of two synchronized time series of different natures [i.e., R-R interval (RRI) and ...

The determination of human creative thinking by employing machine learning classification on EEG signals [PDF]

open access: yesFrontiers in Psychology
Background and objectiveTraditional creativity assessments are limited by subjectivity and high labor costs. Although machine learning (ML) offers objective alternatives, its application to EEG-based creativity evaluation remains scarce. This study aimed

Feature Selection Using Approximate Conditional Entropy Based on Fuzzy Information Granule for Gene Expression Data Classification

open access: yesFrontiers in Genetics, 2021
Classification is widely used in gene expression data analysis. Feature selection is usually performed before classification because of the large number of genes and the small sample size in gene expression data.
