Multivariate multiscale entropy for brain consciousness analysis [PDF]
The recently introduced multiscale entropy (MSE) method accounts for long range correlations over multiple time scales and can therefore reveal the complexity of biological signals. The existing MSE algorithm deals with scalar time series whereas multivariate time series are common in experimental and biological systems.

Estimating perceived image complexity with Multiscale Entropy
The perceived complexity of an image is an image feature that is related to aesthetic pleasure ratings and other subjective visual perceptions. In this study we develop a new computational measure which is largely based on multiscale entropy (MSE ...

Coarse-graining and the Haar wavelet transform for multiscale analysis
Background Multiscale entropy (MSE) has become increasingly common as a quantitative tool for analysis of physiological signals. The MSE computation involves first decomposing a signal into multiple sub-signal ‘scales’ using a coarse-graining algorithm ...

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 ...

Learning Entropy: Multiscale Measure for Incremental Learning [PDF]
First, this paper recalls a recently introduced method of adaptive monitoring of dynamical systems and presents the most recent extension with a multiscale-enhanced approach. Then, it is shown that this concept of real-time data monitoring establishes a novel non-Shannon and non-probabilistic concept of novelty quantification, i.e., Entropy of Learning,

Applying Improved Multiscale Fuzzy Entropy for Feature Extraction of MI-EEG
Electroencephalography (EEG) is considered the output of a brain and it is a bioelectrical signal with multiscale and nonlinear properties. Motor Imagery EEG (MI-EEG) not only has a close correlation with the human imagination and movement intention but ...

Coarse-graining Approaches in Univariate Multiscale Sample and Dispersion Entropy [PDF]
The evaluation of complexity in univariate signals has attracted considerable attention in recent years. This is often done using the framework of Multiscale Entropy, which entails two basic steps: coarse-graining to consider multiple temporal scales ...
