Editing Random forest (section)

==== Preliminaries: Centered forests ====
Centered forest<ref name="breiman2004consistency"/> is a simplified model for Breiman's original random forest, which uniformly selects an attribute among all attributes and performs splits at the center of the cell along the pre-chosen attribute. The algorithm stops when a fully binary tree of level <math>k</math> is built, where <math>k \in\mathbb{N} </math> is a parameter of the algorithm.
