Different seeds give different predictions, but if you grow a sufficiently large number of trees will the predictions for different seeds converge?

    $\begingroup$ Converge $\ne$ deterministic. $\endgroup$ – Tim Jan 20 at 22:39
  • $\begingroup$ This question is basically answered here. stats.stackexchange.com/questions/348245/… Increasing the number of trees is effectively just increasing the number of random trials, so we can apply the usual convergence results, so we know that predictions will tend toward a mean value. $\endgroup$ – Sycorax says Reinstate Monica Jan 21 at 3:00

I would guess not, because the hyperparameter ‘mtry’ still injects randomness into the features that are included during a particular run, not to mention the randomness in the cases selected during cross validation. If anything I would suspect it becomes ‘more deterministic’ as mtry approaches # of features.
