tianchi-shop-location-competition's Introduction

商场中精确定位用户所在店铺: 地址

代码说明

  • 第七名队伍的初赛代码，复赛思路和初赛基本一致，由本人notebook代码整理过来，没有运行过，如有问题欢迎反馈
  • 特征名含义还是比较容易理解的，所以就不特别注释说明了
  • 多分类基本与麦芽的代码相同，初赛A榜0.905，代码中提供了一个注释掉的备选参数，由于时间问题没来得及跑，线下来看应该会好一个百分点左右
  • 最终模型为rank模型（lambdarank），除了需要设置分组外用法与其它模型相同，

代码使用说明

  • gen_samples.py: 多分类产生候选样本
  • model.py: 提取特征，训练模型
