Random Forest nuances

The GC_Random_Forest.pdf file consists of the 500 trees which serve as the homogeneous learners in the random forest ensemble. It is well known that a decision tree has a nice and clear interpretation. This is because it shows how one traverses the path to a terminal node. The random selection of features at each split and the bootstrap samples lead to the setting up of the random forest.
