Class CvGBTreesParams

java.lang.Object
  org.opencv.ml.CvDTreeParams
      org.opencv.ml.CvGBTreesParams

public class CvGBTreesParams
extends CvDTreeParams

GBT training parameters.

The structure contains parameters for each single decision tree in the ensemble, as well as the whole model characteristics. The structure is derived from "CvDTreeParams" but not all of the decision tree parameters are supported: cross-validation, pruning, and class priorities are not used.
