    v2 v3  
    55Friedmans "Stochasic Gradient Boosting" (1999) could be implemented for regression and classification problems.

    7 One important question is where the gradient for our target functions is implemented. In gradient boosting we need to use the correct gradient which is appropriate for the currently selected fitness function.
     7Since version 3.3.12 there is a specific implementation of gradient boosted trees. It would be great if we could also implement gradient boosting as a meta learner that uses any regression algorithm as the base learner.
