本仓库是 ETT (Electricity Transformer Temperature) 数据集转换为 Apache TsFile 格式的版本。
ETT 记录了中国两个地区的电力变压器在两年内的运行数据,是长序列时间序列预测(LSTF)的常用基准。每个数据点包含目标值 油温(Oil Temperature, OT) 和 6 个电力负载特征。原始数据按两种采样频率提供(每小时 / 每 15 分钟),共 4 个序列文件:
| 文件 | 地区 | 采样频率 | 行数 | 时间跨度 |
|---|---|---|---|---|
data/ETTh1.tsfile |
地区 1 | 每小时 | 17,420 | 2016-07-01 ~ 2018-06-26 |
data/ETTh2.tsfile |
地区 2 | 每小时 | 17,420 | 2016-07-01 ~ 2018-06-26 |
data/ETTm1.tsfile |
地区 1 | 每 15 分钟 | 69,680 | 2016-07-01 ~ 2018-06-26 |
data/ETTm2.tsfile |
地区 2 | 每 15 分钟 | 69,680 | 2016-07-01 ~ 2018-06-26 |
| 列名 | 含义 | 类型 |

HULL |
High UseLess Load(高无用负载) | FLOAT |
MUFL |
Middle UseFul Load(中有用负载) | FLOAT |
MULL |
Middle UseLess Load(中无用负载) | FLOAT |
LUFL |
Low UseFul Load(低有用负载) | FLOAT |
LULL |
Low UseLess Load(低无用负载) | FLOAT |

zhouhaoyi/ETDataset 的 4 个原始 CSV(HuggingFace 上的 ETDataset/ett 是一个 Python 加载脚本,运行时拉取这些 CSV 并 reshape 成 GluonTS 风格的滚动窗口样本;本仓库转换的是底层原始 CSV,未使用其 reshape 后的 train/val/test 滚动窗口格式 —— 那只是同一条连续序列的索引视图)。.tsfile**,不合并;保留完整两年序列,不做 train/val/test 切分。date 字符串列(YYYY-MM-DD HH:MM:SS)解析为 INT64 毫秒时间戳。原 date 字符串列不再单独保留 —— 其信息已无损进入 Time 列。HUFL/HULL/MUFL/MULL/LUFL/LULL/OT 共 7 列,均保存为单精度 FLOAT。date → Time(无损);7 个数值列全部保留。from tsfile import TsFileReader
