摘要翻译:
脑电(EEG)信号的解释可能会因混淆伪影而变得复杂。伪影检测在脑电信号的观察和分析中起着重要的作用。可以利用包含在电极位置中的空间信息来准确地检测伪影。然而,当使用更少的电极时,可用的空间信息就更少,从而更难检测伪影。在本研究中,我们研究了深度学习算法CNN-LSTM在几种信道配置下的性能。与标准的22通道脑电图相比,每种配置都被设计成最小化空间信息丢失量。使用8到20个通道的系统灵敏度在33%到37%之间,假警报在每24小时[38,50]的范围内。当信道数量进一步减少时,假警报急剧增加(例如,每24小时超过300起)。一个使用所有22个通道的系统的基线性能是39%的灵敏度和23个假警报。由于22通道系统是唯一包含参考通道的系统,随着通道数量的减少,虚警率的迅速增加突出了保留参考通道以减少伪影的重要性。这一警示性结果很重要,因为不同类型的EEGs之间最大的区别之一是所使用的参考通道类型。

英文摘要:
  Interpretation of electroencephalogram (EEG) signals can be complicated by obfuscating artifacts. Artifact detection plays an important role in the observation and analysis of EEG signals. Spatial information contained in the placement of the electrodes can be exploited to accurately detect artifacts. However, when fewer electrodes are used, less spatial information is available, making it harder to detect artifacts. In this study, we investigate the performance of a deep learning algorithm, CNN-LSTM, on several channel configurations. Each configuration was designed to minimize the amount of spatial information lost compared to a standard 22-channel EEG. Systems using a reduced number of channels ranging from 8 to 20 achieved sensitivities between 33% and 37% with false alarms in the range of [38, 50] per 24 hours. False alarms increased dramatically (e.g., over 300 per 24 hours) when the number of channels was further reduced. Baseline performance of a system that used all 22 channels was 39% sensitivity with 23 false alarms. Since the 22-channel system was the only system that included referential channels, the rapid increase in the false alarm rate as the number of channels was reduced underscores the importance of retaining referential channels for artifact reduction. This cautionary result is important because one of the biggest differences between various types of EEGs administered is the type of referential channel used.
