Sleep staging is one of the most important tasks on the context of sleep studies. From more than 40 years the gold standard to the characterization of patient's sleep is the use of the rules proposed by Rechtschaffen and Kales (R&K). However this method has the limitation of the unnatural assignment of discrete stages instead of doing it in a continuous manner. As part of a more general framework, this paper reports an automatic method for the characterization of the R&K's awake sleep stage through the use of fuzzy reasoning. A continuous evolution of the wakefulness state of the patient during the night is provided as output.
睡眠分期是睡眠研究背景下最重要的任务之一。四十多年来，用于描述患者睡眠的金标准是使用由 Rechtschaffen 和 Kales（R&K）提出的规则。然而，这种方法存在局限性，即采用离散阶段的非自然划分方式，而非连续划分。作为一个更通用框架的一部分，本文报告了一种通过模糊推理来描述 R&K 清醒睡眠阶段的自动方法。该方法的输出是患者夜间清醒状态的连续演变情况。
