关于stacking特征方面
想请问stacking特征是怎么体现的呢，理解的是分两层，那么每一层的分类器都是什么呢，谢谢
统计特征
大佬能解释下，统计特征对于分类的帮助吗？
例如，total_fee中统计出现多的月付费，会对应某一个套餐？
另外，一般Cat和Num交互，会以cat为groupby的输入列，Num为统计列。大佬为什么会统计Cat和Num一起出现的次数？有什么特别的依据吗？
感谢！
模型训练
想问一下，为什么你在最后训练的时候要针对不同的套餐类型分别进行训练预测，对于训练集的选取也没看懂，而且一个做了交叉验证，一个没做交叉验证，不太懂，我是一个小白，能讲解一下吗
数据集提取码错误
关于word2vec的问题
楼主你好，从你的github学到很多东西，谢谢。
我想请问，为什么要对4个月的费用进行word2vec训练？
能解释一下吗？新手
