Identifying genes associated with Parkinson's disease plays an extremely important role in the diagnosis and treatment of Parkinson's disease. In recent years, based on the guilt-by-association hypothesis, many methods have been proposed to predict disease-related genes, but few of these methods are designed or used for Parkinson's disease gene prediction. In this paper, we propose a novel prediction method for Parkinson's disease gene prediction, named N2A-SVM. N2A-SVM includes three parts: extracting features of genes based on network, reducing the dimension using deep neural network, and predicting Parkinson's disease genes using a machine learning method. The evaluation test shows that N2A-SVM performs better than existing methods. Furthermore, we evaluate the significance of each step in the N2A-SVM algorithm and the influence of the hyper-parameters on the result. In addition, we train N2A-SVM on the recent dataset and used it to predict Parkinson's disease genes. The predicted top-rank genes can be verified based on literature study.
识别与帕金森病相关的基因在帕金森病的诊断和治疗中起着极其重要的作用。近年来,基于关联有罪假设,人们提出了许多方法来预测疾病相关基因,但这些方法中很少有专门设计或用于帕金森病基因预测的。在本文中,我们提出了一种用于帕金森病基因预测的新方法,名为N2A-SVM。N2A-SVM包括三个部分:基于网络提取基因特征、使用深度神经网络进行降维以及使用机器学习方法预测帕金森病基因。评估测试表明,N2A-SVM的性能优于现有方法。此外,我们评估了N2A-SVM算法中每个步骤的重要性以及超参数对结果的影响。此外,我们在最新数据集上训练了N2A-SVM,并使用它来预测帕金森病基因。预测出的排名靠前的基因可以通过文献研究进行验证。
