数据获取与解析 data_cr = pd.read_csv('creditcard.csv' , encoding='latin-1') #读取数据 data_cr.head() #查看表格默认前5行 从上面可以看出,数据为结构化数据,不需要抽特征转化,但特征Time和Amount的数据规格和其他特征不一样,需要对其做特征做特征缩放。 data_cr.shape #查看数据集的大小 本数据集大...
通过利用信用卡的历史交易数据,进行机器学习,构建信用卡反欺诈预测模型,提前发现客户信用卡被盗刷的事件。 数据集介绍 数据集(Credit Card Fraud Detection)包含由欧洲持卡人于2013年9月使用信用卡进行交的数据。此数据集显示两天内发生的交易,其中284,807笔交易中有492笔被盗刷。数据集非常不平衡,积极的类(被盗刷)...

This competition is an example of supervised machine learning classification. Supervised machine learning uses algorithms to train a model to find patterns in a dataset with target labels and features. It then uses the trained model to predict the target labels on a new dataset’s...
