Hello，看了您的文档里面有写“直接使用 lightgbm 帮我们去选择特征，一组组的放进去”具体做法是怎样呢？
例如：brand和price特征交叉之后这组新的特征加上原来的特征放进lightgbm训练过后，看feature_importance吗？
刚开始学习数据挖掘相关工作，期待您的回复
请问你的dg-gont效果能复现出来吗
你好，看了你的代码深受启发。但也发现了一个问题：神经网络模型的输入是512， 但是真实数据维度不是512吧？ 期待你的回复
你好，请问代码当中使用 price 与分类特征作交叉时，由于测试集并没有 price ，那么仅在训练集上得出这一部分特征的意义时什么呢？
