信用卡欺诈表格包
真实开源数据集封装（SKU-02）：Kaggle Credit Card Fraud Detection（ULB）。交易级表格，含 PCA 匿名特征 V1–V28 与极不平衡标签 Class（0=正常, 1=欺诈）。交付 train.csv + schema.yaml + README；上架前请复核 Kaggle/DbCL 许可与署名要求。
提供商： 平台自营
交付形态：文件包
适用场景
1 / 5场景说明
本数据集适用于以下场景：
1
信用卡交易欺诈二分类（Class：0=正常，1=欺诈）
2
极不平衡分类：class_weight、undersample、SMOTE 等方法对比
3
异常检测 / 代价敏感学习教学与基线复现
不适用于：还原真实持卡人身份、替代银行核心风控数据、或宣称可直接上生产授信。
