Repository Details

在医院人造心脏瓣膜置换术后,患者会存在感染风险。由于感染是极少出现的(<1%),因此患者感染数据集存在比较严重的比例不平衡问题。针对这一问题,本项目对原始数据进行了重采样,避免正例缺失问题,分别训练了ANN、RF和SVM三个模型,结果表明,数据重采样对预测F1值影响极大,结果可以参看f1_score.csv。本项目也是Risk Factor Analysis of Device-related Infections: Value of Re-sampling Method on the Real-World Imbalanced Dataset论文的部分内容。
