摘要:

脑电图(EEG)波形的分析对于睡眠障碍的诊断至关重要,如睡眠呼吸暂停和失眠,此外,癫痫发作,癫痫,头部损伤,头晕,头痛和脑肿瘤。在这种情况下,一个重要的任务是识别EEG信号中的可见结构,例如睡眠纺锤波和K复合波。这些结构的识别通常是由人类专家通过视觉检查来执行的,这是一个容易出错并且容易受到偏见影响的过程。因此,有兴趣开发技术的自动分析脑电图。在本文中,我们提出了一个新的遗传编程(GP)框架的特征建设和降维从脑电信号。我们使用这些功能来自动识别来自DREAMS项目的数据上的纺锤体和K-复合体。使用5种不同的分类器,由GP产生的属性集获得了比从PCA或完整属性集获得的AUC分数更好的AUC分数。此外,从所提出的框架获得的结果得到了更好的平衡的特异性和召回比其他模型最近提出的文献。对GP最常用的特征的分析也建议在未来的EEG检查中改进数据采集协议。

英文摘要:

The analysis of electroencephalogram (EEG) waves is of critical importance for the diagnosis of sleep disorders, such as sleep apnea and insomnia, besides that, seizures, epilepsy, head injuries, dizziness, headaches and brain tumors. In this context, one important task is the identification of visible structures in the EEG signal, such as sleep spindles and K-complexes. The identification of these structures is usually performed by visual inspection from human experts, a process that can be error prone and susceptible to biases. Therefore there is interest in developing technologies for the automated analysis of EEG. In this paper, we propose a new Genetic Programming (GP) framework for feature construction and dimensionality reduction from EEG signals. We use these features to automatically identify spindles and K-complexes on data from the DREAMS project. Using 5 different classifiers, the set of attributes produced by GP obtained better AUC scores than those obtained from PCA or the full set of attributes. Also, the results obtained from the proposed framework obtained a better balance of Specificity and Recall than other models recently proposed in the literature. Analysis of the features most used by GP also suggested improvements for data acquisition protocols in future EEG examinations.
