摘要:

微睡眠是一种短暂的睡眠,持续1到30秒。在驾驶过程中检测它对于防止可能夺去许多人生命的事故至关重要。脑电(EEG)与意识和睡眠密切相关,适合检测微睡眠。深度学习在识别大脑状态方面表现出色,但需要足够的数据。然而,在驾驶期间收集微睡眠数据是低效的,并且由于嘈杂的驾驶情况而具有获得差的数据质量的高风险。在家里的夜间睡眠数据比在驾驶过程中的微睡眠数据更容易收集。因此,我们提出了一种利用夜间睡眠EEG的深度学习方法来提高微睡眠检测的性能。我们使用夜间睡眠EEG对U-Net进行预训练以分类5类睡眠阶段,并使用U-Net估计的睡眠阶段来检测驾驶期间的微睡眠。与传统方法相比,这将微睡眠检测性能提高了约30%。我们的方法是基于微睡眠对应于非快速眼动(NREM)睡眠的早期阶段的假设。我们分析了夜间睡眠和微睡眠时的脑电分布,发现微睡眠与NREM睡眠具有相似的分布。我们的研究结果提供了微睡眠和NREM睡眠早期阶段之间相似性的可能性,并有助于预防驾驶过程中的微睡眠。

英文摘要:

A micro-sleep is a short sleep that lasts from 1 to 30 secs. Its detection during driving is crucial to prevent accidents that could claim a lot of people's lives. Electroencephalogram (EEG) is suitable to detect micro-sleep because EEG was associated with consciousness and sleep. Deep learning showed great performance in recognizing brain states, but sufficient data should be needed. However, collecting micro-sleep data during driving is inefficient and has a high risk of obtaining poor data quality due to noisy driving situations. Night-sleep data at home is easier to collect than micro-sleep data during driving. Therefore, we proposed a deep learning approach using night-sleep EEG to improve the performance of micro-sleep detection. We pre-trained the U-Net to classify the 5-class sleep stages using night-sleep EEG and used the sleep stages estimated by the U-Net to detect micro-sleep during driving. This improved micro-sleep detection performance by about 30\% compared to the traditional approach. Our approach was based on the hypothesis that micro-sleep corresponds to the early stage of non-rapid eye movement (NREM) sleep. We analyzed EEG distribution during night-sleep and micro-sleep and found that micro-sleep has a similar distribution to NREM sleep. Our results provide the possibility of similarity between micro-sleep and the early stage of NREM sleep and help prevent micro-sleep during driving.
