大佬请教下comm.py中FEED_INFO_FRT需要自己写嘛？根据frt.py改一下。小白不太懂
你把comm.py里最后的注释去掉就可以了

comm.py里面负采样那块可以注释了！对nn影响很大，然后我做的一些统计特征对nn似乎有也负面影响。这样看来，如果好好处理视频冷启动那部分测试样本，nn会表现更好。可以单独做一个冷启动的模型。

lgb吗？lgb很多特征没加，昨天已经更新了，nn的话代码里面有点bug，也已经修复了。。建议根据线下来看，这样可以省提交机会

你的模型线上只有0.60。能问一下为什么吗？

多半因为负采样了，用nn的话特征要筛选下，参数很好调下(epoch),不能负采样，不能负采样！！

大佬，我想请教一下更新后的LGB可以是跑到64的版本吗，我跑了一下大概62左右
