Forest-RK: A New Random Forest Induction Method

  title={Forest-RK: A New Random Forest Induction Method},
  author={Simon Bernard and Laurent Heutte and S{\'e}bastien Adam},
In this paper we present our work on the parametrization of Random Forests (RF), and more particularly on the number K of features randomly selected at each node during the tree induction process. It has been shown that this hyperparameter can play a significant role on performance. However, the choice of the value of K is usually made either by a greedy search that tests every possible value to choose the optimal one, either by choosing a priori one of the three arbitrary values commonly used… CONTINUE READING
