我们为液质联用(LCMS)血清样本的数据预处理、生物标记物选择和分类提供了一条管道,以产生莱姆病的前瞻性诊断试验。我们利用稀疏支持向量机(SSVM)、迭代特征去除(IFR)和k重特征排序等机器学习工具来选择几个生物标志物,并建立莱姆病的判别模型。我们报告了基于隔离的LCMS血清样本集的我们的模型的98.13%的测试平衡成功率(BSR)。所采用的方法是通用的,可以很容易地适用于其他LC MS或代谢组学数据集。
We provide a pipeline for data preprocessing, biomarker selection, and classification of liquid chromatography–mass spectrometry (LCMS) serum samples to generate a prospective diagnostic test for Lyme disease. We utilize tools of machine learning (ML), e.g., sparse support vector machines (SSVM), iterative feature removal (IFR), and k-fold feature ranking to select several biomarkers and build a discriminant model for Lyme disease. We report a 98.13% test balanced success rate (BSR) of our model based on a sequestered test set of LCMS serum samples. The methodology employed is general and can be readily adapted to other LCMS, or metabolomics, data sets.
