Challenge yourself with the following question.
Question 1
Suppose the "sum of the split score" variable importance of feature f1
is greater than the "number of nodes" variable importance of feature f2.
In this case, which of the following statements is correct?
f1 is more important than f2.
f1 is less important than f2.
f1 is neither more important nor less important than f2.
Well done.
