* [jvm-packages] Ensure the native library is loaded once Previously any class using XGBoostJNI queried NativeLibLoader to make sure the native library is loaded. This commit moves the initXGBoost call to XGBoostJNI, effectively delegating the initialization to the class loader. Note also, that now XGBoostJNI would NOT suppress an IOException if it occured in initXGBoost. * [jvm-packages] Fused JNIErrorHandle with XGBoostJNI There was no reason for having a separate class.
eXtreme Gradient Boosting
Documentation | Resources | Installation | Release Notes | RoadMap
XGBoost is an optimized distributed gradient boosting library designed to be highly efficient, flexible and portable. It implements machine learning algorithms under the Gradient Boosting framework. XGBoost provides a parallel tree boosting (also known as GBDT, GBM) that solve many data science problems in a fast and accurate way. The same code runs on major distributed environment (Hadoop, SGE, MPI) and can solve problems beyond billions of examples.
