class mlpack::tree::DecisionTreeRegressor< FitnessFunction, NumericSplitType, CategoricalSplitType, DimensionSelectionType, NoRecursion >

Its behavior can be controlled via its template arguments.

The class inherits from the auxiliary split information in order to prevent an empty auxiliary split information struct from taking any extra size.
