论文摘要

近年来,使用传统的无监督的机器学习方法和监督的深度学习模型,有许多研究病例,用于诊断帕金森氏病(PD),并使用脑磁共振成像(MRI)。但是,无监督的学习方法不擅长在MRI中提取准确的特征,并且很难在PD领域收集足够的数据来满足训练深度学习模型的需求。此外,大多数现有研究基于单视图MRI数据,其中数据特征不够足够。因此,在本文中,为了解决上述缺点,我们提出了一个新颖的半监督学习框架,称为半监督的多视图学习群集结构架构技术(SMC)。该模型首先引入了滑动窗口方法以掌握不同的特征,然后使用线性判别分析(LDA)的维度降低算法来处理具有不同特征的数据。最后,在多个功能视图上采用了传统的单视聚类和多视图聚类方法来获得结果。实验表明,我们所提出的方法优于针对聚类效应的最先进的无监督学习模型。结果,可以注意到,我们的工作可能有助于提高通过现实的医疗环境中以前标记和随后未标记的医疗MRI数据识别PD的有效性。

In recent years, there are many research cases for the diagnosis of Parkinson's disease (PD) with the brain magnetic resonance imaging (MRI) by utilizing the traditional unsupervised machine learning methods and the supervised deep learning models. However, unsupervised learning methods are not good at extracting accurate features among MRIs and it is difficult to collect enough data in the field of PD to satisfy the need of training deep learning models. Moreover, most of the existing studies are based on single-view MRI data, of which data characteristics are not sufficient enough. In this paper, therefore, in order to tackle the drawbacks mentioned above, we propose a novel semi-supervised learning framework called Semi-supervised Multi-view learning Clustering architecture technology (SMC). The model firstly introduces the sliding window method to grasp different features, and then uses the dimensionality reduction algorithms of Linear Discriminant Analysis (LDA) to process the data with different features. Finally, the traditional single-view clustering and multi-view clustering methods are employed on multiple feature views to obtain the results. Experiments show that our proposed method is superior to the state-of-art unsupervised learning models on the clustering effect. As a result, it may be noted that, our work could contribute to improving the effectiveness of identifying PD by previous labeled and subsequent unlabeled medical MRI data in the realistic medical environment.
