## 1、Data folders
| 文件夹 | 相关描述 |
| :----------------------------: | :--------------------------------------------------: |
| 2016 PHM Data Challenge、data | 这两个文件夹均是存放原始数据集 |
| Processed data set | 存放经模态划分后的训练数据集、测试训练集、验证数据集 |
| model predict image | 存放经模态划分后的存放相关模型的预测走势图 |
| two mode division experiment | 存放对数据进行双模态划分后的相关文件 |
| three mode division experiment | 存放对数据进行三模态划分后的相关文件 |
## 2、Code files
