Decision Tree Learner

Dear all,

I would like to force include a particular column (hard skills) into my decision tree. However, as I am using information gain ratio, this column is not shown in my decision tree, perhaps due to it having lower information gain compared to the rest of the column. Are there ways to force include a column into the decision tree other than using the Force Root Split Column? Attached is my workflow for reference.

Hi @chrishy

I tried out with your workflow and I think the trick is that you are forcing the minimum number of records per nodes required to be 10, which is a bit high considering your data sample (unless this is just a subset of your data). If you try changing it to 4, for instance, it works.
