WitrynaUsing R, random forests is able to correctly classify about 90% of the objects. One of the things we want to try and do is create a sort of "certainty score" that will quantify how confident we are of the classification of the objects. We know that our classifier will never be 100% accurate, and even if high accuracy in predictions is achieved ...

WitrynaThe answer, below, is very good. The intuitive answer is that a decision tree works on splits and splits aren't sensitive to outliers: a split only has to fall anywhere between two groups of points to split them. – Wayne. Dec 20, 2015 at 15:15.
