English(EN) Wolff-Parkinson-White Detection at 471:1 Class Imbalance: A Leakage-Controlled Study of the Data Bottleneck

研究利用不平衡心电图数据解决罕见心脏病检测问题

研究人员利用大量心电图(ECG)记录数据集,对 Wolff-Parkinson-White(WPW)综合征(一种罕见的心脏病)的检测进行了研究。该研究旨在解决显著的类别不平衡问题,在 66,951 条记录中仅有 142 例 WPW 病例。在防止数据泄露的受控协议下,比较了包括不同信号表示和自监督预训练在内的各种检测方法。研究结果表明,增加模型的多元化和容量并未显著提高检测性能,甚至一个特征联合模型也仅能与一个简单的两成员投票模型相匹配。错误分析显示,漏诊的病例通常具有较窄的 QRS 波群,而一些假阳性则是被错误标记的记录。 AI

影响 这项研究突显了在类别不平衡数据集上应用人工智能进行罕见病检测所面临的挑战,可能为未来医学人工智能的发展提供参考。

    Wolff-Parkinson-White 471:1 类不平衡检测:数据瓶颈的泄漏控制研究

    arXiv:2608.14633v1 Announce Type: cross Abstract: Wolff-Parkinson-White (WPW) syndrome is a congenital cardiac pre-excitation, clinically important and often missed on the resting 12-lead ECG. Detection is hard: the signature is subtle and the condition rare. We pool two public 1…
