Speech Endpoint Detection Based on Multi-scale Sample Entropy and Threshold [PDF]

open access: yesJisuanji gongcheng, 2016
In order to overcome the defect that sample entropy can be falsely detected due to its sensitivity to the suddenly changing noise,this paper proposes a speech endpoint detection algorithm.This algorithm does the multi-scale transform for the speech ...

Classification of Five-Second Epileptic EEG Recordings Using Distribution Entropy and Sample Entropy

open access: yesFrontiers in Physiology, 2016
Epilepsy is an electrophysiological disorder of the brain, the hallmark of which is recurrent and unprovoked seizures. Electroencephalogram (EEG) measures electrical activity of the brain that is commonly applied as a non-invasive technique for seizure ...

A Multithreaded Algorithm for the Computation of Sample Entropy

open access: yesAlgorithms, 2023
Many popular entropy definitions for signals, including approximate and sample entropy, are based on the idea of embedding the time series into an m-dimensional space, aiming to detect complex, deeper and more informative relationships among samples. However, for both approximate and sample entropy, the high computational cost is a severe limitation ...

Entropy Approximation by Machine Learning Regression: Application for Irregularity Evaluation of Images in Remote Sensing

open access: yesRemote Sensing, 2022
Approximation of entropies of various types using machine learning (ML) regression methods are shown for the first time. The ML models presented in this study define the complexity of the short time series by approximating dissimilar entropy techniques ...
