Respected sir,

I am working on a project based on random forest.I saw one ppt (Rec08_Oct21.ppt)(www.cs.cmu.edu/~ggordon/10601/.../rec08/Rec08_Oct21.ppt)
regarding random forest creation. I wanted to ask a question.
After scanning through the randomly selected features and their Information gain value, we select the feature with the max value of IG for feature j. Then, how do we split using this information?? How do we proceed after this?

Thanks in advance!:)
