public final class RandomForestClassificationModel extends PredictionModel<Vector,RandomForestClassificationModel> implements scala.Serializable
Random Forest
model for classification.
It supports both binary and multiclass labels, as well as both continuous and categorical
features.
param: _trees Decision trees in the ensemble.
