提出新框架与数据集,让机器学习更贴近临床睡眠觉醒检测需求。

ALPEC: A Comprehensive Evaluation Framework and Dataset for Machine Learning-Based Arousal Detection in Clinical Practice

  • 聚焦觉醒起始点检测,匹配临床实际标注习惯
  • 构建包含多模态信号的新型睡眠数据集(CPS)
  • 适合临床研究者与医疗AI开发者参考使用

睡眠中觉醒的检测对睡眠障碍诊断至关重要。然而,机器学习在临床应用中受限于临床规范与算法方法之间的不匹配:临床通常仅标注觉醒起始点,而机器学习模型依赖起止点标注;且缺乏针对临床需求的标准化评估方法。本文提出一种新的后处理与评估框架ALPEC,强调觉醒事件的近似定位与精确计数。建议机器学习研究聚焦觉醒起始点检测,以契合临床实践。我们引入一个全新的综合性多导睡眠图数据集(CPS),反映上述临床标注约束,并包含现有数据集中未涵盖的生理模态。本文同时发布该数据集,展示多模态数据在觉醒起始点检测中的优势。研究成果显著推动了基于机器学习的觉醒检测在临床环境中的整合,缩小技术进步与临床需求间的差距。

原文摘要 · Abstract (English)

Detecting arousals in sleep is essential for diagnosing sleep disorders. However, using Machine Learning (ML) in clinical practice is impeded by fundamental issues, primarily due to mismatches between clinical protocols and ML methods. Clinicians typically annotate only the onset of arousals, while ML methods rely on annotations for both the beginning and end. Additionally, there is no standardized evaluation methodology tailored to clinical needs for arousal detection models. This work addresses these issues by introducing a novel post-processing and evaluation framework emphasizing approximate localization and precise event count (ALPEC) of arousals. We recommend that ML practitioners focus on detecting arousal onsets, aligning with clinical practice. We examine the impact of this shift on current training and evaluation schemes, addressing simplifications and challenges. We utilize a novel comprehensive polysomnographic dataset (CPS) that reflects the aforementioned clinical annotation constraints and includes modalities not present in existing polysomnographic datasets. We release the dataset alongside this paper, demonstrating the benefits of leveraging multimodal data for arousal onset detection. Our findings significantly contribute to integrating ML-based arousal detection in clinical settings, reducing the gap between technological advancements and clinical needs.
