摘要： 提出将脑电信号与眼动信号的精细复合多尺度熵作为睡眠分期依据，利用多层次支持向量机的机器学习算法对睡眠进行自动分期.利用精细复合多尺度熵对睡眠信号进行特征提取，选用脑电以及眼电通道的信号，以保证输入特性的可靠性，并通过3层支持向量机实现了睡眠的自动分期.结果表明，分类器的输入参数可由熵值曲线的变化特征来确定.基于精细复合多尺度熵的多层次支持向量机算法的睡眠分期准确率达到85.3%，与已有的分类算法相比，所提出的算法更加均衡，且整体分类效果更佳.

Abstract: Sleep scoring is an important research direction in medical research and clinical medicine. Traditional visual scoring method is based on scoring rules, which is a time consuming and subjective procedure. Therefore an automatic sleep staging method based on refined composite multi-scale entropy (CMSE) and multi-level support vector machine is proposed. Firstly, to ensure the reliability of the input characteristics, refined CMSE is extracted as the feature input and two channels of electroencephalogram (EEG) and electrooculogram (EOG) are used. Then a three-layer support vector machine classification scheme is applied to classify sleep stages. Specifically, the inputs of each layer are obtained according to the trend of the entropy curves. The overall accuracy of the proposed method is 85.3%. Compared with traditional methods, the classification accuracy of the proposed method is more balanced and the global performance is much better.

Key words: sleep scoring, refined, composite multi-scale entropy (CMSE)
