This is great news! I've already re-implemented the new approach in Since the implementation in ranger is based on your code, we might add one of you as a contributor if you like. See also some discussions in imbs-hl/ranger#207 and imbs-hl/ranger#136. |
Hi,
There seems to be a major re-design in version 1.3. If I understand your code correctly, you don't compute the weights (as described in the paper) anymore but just sample one random training observation per node. The quantiles are now computed on the distribution over all trees.
