xfeat:使用GPU和Optuna的灵活的功能工程和探索库
xfeat
|||
使用GPU和柔性特征工程与探索库。
xfeat提供了类似于sklearn的转换类，用于要素工程和探索。与sklearn API不同，xfeat提供了一个数据帧输入，数据帧输出接口。 xfeat支持和数据帧。通过使用cuDF和 ，xfeat可以比原始的熊猫操作快10到30倍地生成特征。
分组汇总基准（）
目标编码基准（）
文档
Optuna的功能选择
目录中提供了更多示例。
快速开始
xfeat提供了一个数据帧输入，数据帧输出接口：
特征工程
可以使用xfeat.Pipeline顺序连接编码器对象。为避免重复相同的特征提取过程，将结果输出为羽毛文件格式很有用。
提供更多编码器类。
