# 最好的版本
| location | score | rank | detail |
| ----------------------------------------------- | --------------- | --- | --------------------- |
| McDonald/McDonald_v4.ipynb | 0.84609425068 | 30 |一个完整的版本1.数据预处理 2.第一层xgboost gbdt rf lgbm knn 五个模型融合 3.第二层模型融合选择SVR|
| code_version_save/wan_8月4号22点11分.ipynb | 0.84751743 | 22 | 增加一个强特 历史平均功率,knn模型不太好,选择xgboost gbdt rf lgbm四个模型,测试过单独增加列 用ID%205 没有效果,分数反而降低至0.846
| code_version_save/wan_8月16号 0.84770610000.ipynb | 0.84770610000 | * | 增加四列 历史平均功率 历史功率A 历史功率B 历史功率C

## 备注
保密工作没有做好,很多队伍在github上检索到了我们的代码,已知的某队伍,部分使用我们的代码最终B榜11名
需要在github上使用英文书写相关信息
对于特征处理方面没有做好,暴力特征+特征选择 初赛A榜预计能到 前10
A榜过拟合比较严重
## 向大佬咨询的强特
他给我发的catboost的训练记录表
![image](https://github.com/wanlida/2018_diantou_PhotovoltaicPowerStation/raw/master/pictures/cat.png)
XX选用的模型是 xgboost gbdt catboost lgbm,我也试了试catboost 感觉使用很不熟练,a榜分数也不高,主要是catboost ;类别型特征需要特殊处理
