This study presents the concept of a computationally efficient machine learning (ML) model for diagnosing and monitoring Parkinson's disease (PD) using rest-state EEG signals (rs-EEG) from 20 PD subjects and 20 normal control (NC) subjects at a sampling rate of 128 Hz. Based on the comparative analysis of the effectiveness of entropy calculation methods, fuzzy entropy showed the best results in diagnosing and monitoring PD using rs-EEG, with classification accuracy () of ~99.9%. The most important frequency range of rs-EEG for PD-based diagnostics lies in the range of 0-4 Hz, and the most informative signals were mainly received from the right hemisphere of the head. It was also found that significantly decreased as the length of rs-EEG segments decreased from 1000 to 150 samples. Using a procedure for selecting the most informative features, it was possible to reduce the computational costs of classification by 11 times, while maintaining an ~99.9%. The proposed method can be used in the healthcare internet of things (H-IoT), where low-performance edge devices can implement ML sensors to enhance human resilience to PD.
本研究提出了一种使用 128 Hz 采样率的 20 名帕金森病 (PD) 患者和 20 名正常对照 (NC) 患者的静息态脑电图 (rs-EEG) 信号来诊断和监测 PD 的计算效率高的机器学习 (ML) 模型的概念。基于对熵计算方法有效性的比较分析,模糊熵在使用 rs-EEG 诊断和监测 PD 方面表现出最佳结果,分类准确率()约为 99.9%。rs-EEG 对 PD 诊断最重要的频率范围位于 0-4 Hz 之间,最具信息量的信号主要来自头部的右半球。还发现,随着 rs-EEG 段从 1000 个样本减少到 150 个样本,显著降低。通过选择最具信息量特征的程序,可以将分类的计算成本降低 11 倍,同时保持 99.9%左右的准确率。该方法可用于医疗保健物联网 (H-IoT),其中低性能边缘设备可以实现 ML 传感器,以增强人类对 PD 的适应能力。
