I am afraid that a decision tree HAS direct impact on the forest. Multiple trees averaged give the forest response. It's like saying, one vote in elections has nothing to do with the final decision.

Sure we have heard it many times that it IS a like a brain, and many times it is NOT like a brain. It really depends on your intended audience, but it is not worth picking on and it feels like the tabs/spaces problem. BTW: tabs of course!

I think the poster meant real world wooded forests as an example. As in, the human brain is as distant from this mathematical construct as an actual forest with bears is from decision trees.

Well, that is possible. I have probably worked too much with trees and forests.
