The vast majority of sleep disturbances are caused by various types of sleep arousal. To diagnose sleep disorders and prevent health problems such as cardiovascular disease and cognitive impairment, sleep arousals must be accurately detected. Consequently, sleep specialists must spend considerable time and effort analyzing polysomnography (PSG) recordings to determine the level of arousal during sleep. The development of an automated sleep arousal detection system based on PSG would considerably benefit clinicians. We quantify the EEG-ECG by using Lyapunov exponents, fractals, and wavelet transforms to identify sleep stages and arousal disorders. In this paper, an efficient hybrid-learning method is introduced for the first time to detect and assess arousal incidents. Modified drone squadron optimization (mDSO) algorithm is used to optimize the support vector machine (SVM) with radial basis function (RBF) kernel. EEG-ECG signals are preprocessed samples from the SHHS sleep dataset and the PhysioBank challenge 2018. In comparison to other traditional methods for identifying sleep disorders, our physiological signals correlation innovation is much better than similar approaches. Based on the proposed model, the average error rate was less than 2%-7%, respectively, for two-class and four-class issues. Additionally, the proper classification of the five sleep stages is determined to be accurate 92.3% of the time. In clinical trials of sleep disorders, the hybrid-learning model technique based on EEG-ECG signal correlation features is effective in detecting arousals.
绝大多数睡眠障碍是由各种类型的睡眠觉醒引起的。为了诊断睡眠障碍和预防心血管疾病和认知障碍等健康问题,必须准确检测睡眠觉醒。因此,睡眠专家必须花费大量的时间和精力分析多导睡眠图 (PSG) 记录,以确定睡眠期间的觉醒水平。基于 PSG 开发自动睡眠觉醒检测系统将极大地有益于临床医生。我们使用李雅普诺夫指数、分形和小波变换来量化 EEG-ECG,以识别睡眠阶段和觉醒障碍。在本文中,首次引入了一种有效的混合学习方法来检测和评估觉醒事件。使用改进的无人机中队优化 (mDSO) 算法优化具有径向基函数 (RBF) 核的支持向量机 (SVM)。EEG-ECG 信号是来自 SHHS 睡眠数据集和 PhysioBank 挑战 2018 的预处理样本。与其他传统的识别睡眠障碍的方法相比,我们的生理信号相关性创新比类似的方法要好得多。基于所提出的模型,对于两类和四类问题,平均错误率分别小于 2%-7%。此外,确定 5 个睡眠阶段的正确分类准确率为 92.3%。在睡眠障碍的临床试验中,基于 EEG-ECG 信号相关特征的混合学习模型技术在检测觉醒方面非常有效。
