Abstract

Parkinson's disease (PD) is classified as a neurological, progressive illness brought on by cell death in the posterior midbrain. Early PD detection will assist doctors in reducing the disease's consequences. A collection of skilled models that may be applied to regression as well as classification is known as artificial intelligence (AI). PD can be detected using a variety of dataset formats, including text, speech, and picture datasets. For the purpose of classifying Parkinson's disease, this study suggests merging deep with machine learning recognition approaches. The three primary components of the suggested approach are designed to enhance the accuracy of Parkinson's disease early diagnosis. These sections cover the topics of categorising, combining, and separating. Convolutional Neural Networks (CNN) as well as attention procedures are used to create feature extractors. The related motion signals are fed to a combination of convolutional neural network and long-short-memory model for feature extraction. Besides, for the classification of patients from non-suffers of Parkinson's disease, Random Forest, Logistic Regression, Support Vector Machine, Extreme Boot Classifier, and voting classifier were used. Our result shows that for the PD handwriting and related motion datasets, using the proposed CNN with an attention and voting classifier yields 99.95% accuracy, 99.99% precision, 99.98% sensitivity, and 99.95% F1-score. Based on these results, it is warranted to conclude that the proposed methodology of feature extraction from photos of handwriting and relating motor symptoms, fusing of those features, and following it with a voting classifier yields excellent results for PD classification.

摘要

帕金森病(PD)被归类为一种由中后脑细胞死亡引起的神经退行性疾病。早期 PD 的检测将有助于医生减轻疾病的后果。人工智能(AI)是一种可以应用于回归和分类的多种熟练模型的集合。可以使用多种数据集格式(包括文本、语音和图片数据集)来检测 PD。为了对帕金森病进行分类,本研究提出将深度学习与机器学习识别方法相结合。所提出方法的三个主要部分旨在提高帕金森病早期诊断的准确性。这些部分涵盖分类、组合和分离的主题。卷积神经网络(CNN)和注意力程序用于创建特征提取器。将相关运动信号输入到卷积神经网络和长短记忆模型的组合中,以进行特征提取。此外,为了对帕金森病患者和非帕金森病患者进行分类,使用随机森林、逻辑回归、支持向量机、极端引导分类器和投票分类器。我们的结果表明,对于 PD 手写和相关运动数据集,使用带有注意力和投票分类器的建议 CNN 可达到 99.95%的准确率、99.99%的精度、99.98%的灵敏度和 99.95%的 F1 得分。基于这些结果,可以得出结论,从手写和相关运动症状的照片中提取特征、融合这些特征以及随后使用投票分类器的建议方法对 PD 分类产生了出色的结果。
