DefaultData and PPDaiData

DefaultData dataset is obtained from the UCI machine learning library (Asuncion & Newman, 2007). PPDai dataset is obtained from customer data from a Chinese P2P lending platform named PaiPaiDai .A brief description of these datasets is shown in Table 1. DefaultData dataset contains 30000 instances including 23364 non-default instances and 6636 default instances. Each instance contains 24 features (15 numeric features and 9 categorical features). PPDai dataset contains 55596 instances including 48413 non-default instances and 7183 default instances. Each instance contains 29 features (22 numeric features and 7 categorical features).DefaultData数据集源自UCI机器学习库（Asuncion & Newman, 2007）。PPDai数据集源自中国P2P网贷平台拍拍贷（PaiPaiDai）的客户数据。两类数据集的简要说明详见表1。DefaultData数据集共包含30000条实例，其中非违约实例23364条、违约实例6636条；每条实例涵盖24个特征，包含15个数值型特征与9个分类特征。PPDai数据集共包含55596条实例，其中非违约实例48413条、违约实例7183条；每条实例涵盖29个特征，包含22个数值型特征与7个分类特征。
