Electricity Transformer Temperature (ETTh1, ETTh2, ETTm1, ETTm2)

该数据集记录了两年内每小时（ETTh1和ETTh2）以及每15分钟（ETTm1和ETTm2）的电力变压器温度数据，包含了电力变压器的7项油量和负载特征。此外，这些数据集按照时间顺序以6:2:2的比例被划分为训练集、验证集和测试集。该数据集涉及多特征（7个特征），其任务是进行多变量预测。

This dataset contains hourly (ETTh1 and ETTh2) and 15-minute (ETTm1 and ETTm2) power transformer temperature data over a two-year period, including seven oil quantity and load-related features of power transformers. Additionally, these datasets are split into training, validation, and test sets in a 6:2:2 ratio following the strict chronological order of the time series. This multi-feature dataset, which consists of a total of 7 features, is intended for multivariate forecasting tasks.
