代码说明

data

存放原始的数据文件,包括:

  • 训练数据,draft_data_train.csv
  • A榜测试数据,d_test_A_20180102
  • B榜测试数据,d_test_B_20180128.csv

数据分析与特征提取

  • feature_extract.py,提取特征,在data目录下生成feature目录,存放特征文件
  • offline_data_extract.py,提取线下训练与测试集

classification

  • xgb_hp95.py,训练xgboost分类器,判断'id'的血糖是否大于95百分位数
  • xgb_lp30.py,训练xgboost分类器,判断'id'的血糖是否小于30百分位数
  • series_model.py,训练一系列分类器,包括MLP,RF,XGB等,模型均保持在model/classification文件夹下
  • level_elimination.py,加载一些列保存的分类模型,对test数据集进行瀑布流筛选,保留top150

MLP_regression

  • yy_tensorflow.py,训练MLP回归模型,并同时对测试集进行回归预测

model

  • classification 文件夹保存分类器的各类模型
  • regression 文件夹保存回归其的各类模型(lightdm模型除外)

regression

  • xgb.py 训练xgboost回归器

  • dart.py,训练dart回归器

  • lightdm.py,训练lightdm回归器

  • rf.py,训练lightdm回归器

  • gen_submission.py,生成提交文件,融合了四个回归模型的结果。

  • post_process.py,使用分类模型的预测结果,对回归预测的结果进行后处理
