I found this article on Downsampling in combination with Upweighting: https://developers.google.com/machine-learning/data-prep/construct/sampling-splitting/imbalanced-dat...
The article's authors elaborate that artificial weights put on the Downsampled class help in correcting the bias in model scores (F1 score) -- which is important because bias is a side-effect of Downsampling the training data. So now I’m wondering if DataRobot already automatically does Upweighting?
