       * Gradient-Boosted Trees (GBTs) (http://en.wikipedia.org/wiki/Gradient_boosting)
       * learning algorithm for classification.
       * It supports binary labels, as well as both continuous and categorical features.
       * Note: Multiclass labels are not currently supported.
       *
       * The implementation is based upon: J.H. Friedman. "Stochastic Gradient Boosting." 1999.
       *
       * Notes on Gradient Boosting vs. TreeBoost:
       *  - This implementation is for Stochastic Gradient Boosting, not for TreeBoost.
       *  - Both algorithms learn tree ensembles by minimizing loss functions.
       *  - TreeBoost (Friedman, 1999) additionally modifies the outputs at tree leaf nodes
       *    based on the loss function, whereas the original gradient boosting method does not.
       *  - We expect to implement TreeBoost in the future:
