Undersampling, Oversampling, and weighing
How can I populate my data so I only get undersampling sampling technique without modeling. I need to do the same for oversampling and weighing. I am trying to run xgboost with these three sampling techniques (one at a time of course). So, I need one dataset that shows undersampling, a different dataset for oversampling, and a third dataset for weighing. Thank you.
