Tom Kraljevic commented: I wonder if it makes more sense to allow providing a metadata description of the forest, so you can specify the details of each tree one-by-one in full detail.
Then parameters like this can be layered on top.

Add the ability to add noise to the
max_depth
parameter in RF and GBM via a newmax_depth_noise_sigma
argument that defaults to 0. If this is greater than zero, it will sample themax_depth
value for each tree from a Gaussian with mean = max_depth and sigma = max_depth_noise_sigma.This will result in trees grown with different values of max_depth, adding greater variability among the trees in the ensemble.
