Classes | |
| class | xgboost::detail::GradientPairInternal< T > |
| Implementation of gradient statistics pair. Template specialisation may be used to overload different gradients types e.g. low precision, high precision, integer, floating point. More... | |
| class | xgboost::GradientPairInt64 |
| Fixed point representation for high precision gradient pair. Has a different interface so we don't accidentally use it in gain calculations. More... | |
