Decision tree with different split criterion than information gain

Tags: ,



I’d like to create a decision tree in python with a different split criterion than information gain, something like “1-information gain” (something like the opposite of impurity measure, like as similarity measure).
Does already exist something like this? paper included.
Thanks

Answer

Yes, it exists. There are many research papers:
