模型文件的xgbcv 和lgbcv函数是不是没有用到cv
我看了模型文件中的xgbcv和lgbcv函数，其中好像没有用到fold参数，也没有做cv吧。好像就是普通的训练。不知道是不是这样。求解答。。
关于代码中变量的含义
请问在cal_cvr函数中新增的特征cvr_gb_ip_day_hour,cvr_gb_ip_app, cvr_gb_ip_app_os分别代表什么意思呢？在这个函数中为什么需要将train的cvr Merge到test数据集中呢？如果需要利用模型单独预测一批数据的话没有训练集的cvr是不是就不行呢？
请问你有对样本标签不平衡做处理吗？
您好，我想学习下您的代码，可以发下相关数据的百度云链接或者其他渠道吗
你好
正在学习你的kernel，不知道是否方便加个QQ或微信交流一下
