Automatic sampling_type in Split Operator
Just one quick question if anyone has any idea on this.
For the Automatic sampling_type in Split Operator, it is said that it will use stratified sampling if the label is nominal, shuffled sampling otherwise.
What if the label is polynominal? It will be used stratified sampling?
Because I have imbalanced classes and I want to split the data as split 1: 75-25, then again split that 75 from split 1 into 75-25 an split 2.
I will save the model from split 2 and input the 25 from the split 1 as the unseen data to test the model.
thanks and regards,
