%description
This tool enables in-database scoring of 'XGBoost' models built in R, by
translating trained model objects into SQL query. 'XGBoost'
<https://github.com/dmlc/xgboost> provides parallel tree boosting (also
known as gradient boosting machine, or GBM) algorithms in a highly
efficient, flexible and portable way. GBM algorithm is introduced by
Friedman (2001) <doi:10.1214/aos/1013203451>, and more details on
'XGBoost' can be found in Chen & Guestrin (2016)
<doi:10.1145/2939672.2939785>.
