天池“资金流入流出预测——挑战baseline”的解决方案,线上效果143.5

项目结构

  1. 数据探索与分析 对于赛题的理解与对数据的分析
  2. 数据探索与分析 对于赛题的理解与对数据的分析
  3. 时间序列规则 采用简单时间序列规则进行预测
  4. 时间序列 采用时间序列模型进行预测(本章节未上传,但不影响继续后面几个章节)
  5. 特征工程 面向机器学习模型进行时间序列特征工程
  6. 建模预测 采用机器学习模型进行建模预测

Q&A

Q: 我在运行您的第6个文件时发现缺少数据,请问是否缺少文件,遇到这个问题可以怎么 处理?
A: 首先您需要先运行05.特征工程生成特征文件保存在./Feature目录下。其次06.建模预测中对Purchase以及Redeem分别建模,因此您需要将05.特征工程中的Purchase替换成Redeem再次运行一遍,以生成Redeem特征。

Q: 您好!在天池竞赛——资金流入流出预测中,在训练模型的时候发现某个文件不存在feature0522.csv,请问是否存在其他脚本,如果有可以发一下吗?
A: feature0522并没有实际生成,您可以读取05.特征工程中生成的purchase_feature_droped_0614.csv文件,在建模时删除特征名中不带有"is"的特征,与feature0522建模效果是等价的。
