Sleep Quality Detection Based on EEG Signals Using Transfer Support Vector Machine Algorithm

Abstract

BackgroundIn recent years, with the acceleration of life rhythm and increased pressure, the problem of sleep disorders has become more and more serious. It affects people’s quality of life and reduces work efficiency, so the monitoring and evaluation of sleep quality is of great significance. Sleep staging has an important reference value in sleep quality assessment. This article starts with the study of sleep staging to detect and analyze sleep quality. For the purpose of sleep quality detection, this article proposes a sleep quality detection method based on electroencephalography (EEG) signals.Materials and MethodsThis method first preprocesses the EEG signals and then uses the discrete wavelet transform (DWT) for feature extraction. Finally, the transfer support vector machine (TSVM) algorithm is used to classify the feature data.ResultsThe proposed algorithm was tested using 60 pieces of data from the National Sleep Research Resource Library of the United States, and sleep quality was evaluated using three indicators: sensitivity, specificity, and accuracy. Experimental results show that the classification performance of the TSVM classifier is significantly higher than those of other comparison algorithms. This further validated the effectiveness of the proposed sleep quality detection method.

Methodologies and Wearable Devices to Monitor Biophysical Parameters Related to Sleep Dysfunctions: An Overview

“…Some tests estimated the algorithms' performance based on Cohen's kappa. In addition, the study introduced in [82] illustrates a sleep staging method based on EEG signals, which involves signal pre-processing, characteristic parameters detection, and sleep stage identification. The pre-processing operation aims to reduce high-frequency background noise, low-frequency baseline wander, and artifact disturbance, apply a low-pass filter, split signals into 30 s data, and remove baseline drift and artifacts.…”
