Long-term Forecasting Target

[jp-guo]

Thanks for your great work!

In the ETT datasets, the target shoule be the oil temperature (OL), but in the repo I find that OFA seems to predict all 7 features in a single-to-single manner. Also the feature category is not part of the input. So OFA seems to hypothesize that all 7 features are from the same distribution. Is this the same setting with other baseline methods? I find most papers claim they treat OL as the only target feature.

This approach, often referred to as channel-independent, is utilized for multivariable forecasting and has been demonstrated by several previous studies to help mitigate overfitting. Meanwhile, the paper you're examining may focus on univariate forecasting, where operational loss (OL) is the sole objective.
