Knowledge Studio’s Weight of Evidence node is essential to creating scorecard models. The Weight of Evidence node transforms your data so the model can assign points to every bin and these points will eventually add up to the scorecard. Knowledge Studio uses Altair’s patented decision trees to bin ordinal and some continuous variables. If the bins don’t make business sense, you can optimize them automatically by binning them for monotonicity and disallowing pure nodes. Knowledge Studio can optimize all variables in your dataset with a single click. You can also edit the splits if you have business reasons to bin your variables differently. Once Knowledge Studio has transformed your variables, you can see the code that created the transformation.
