- Avoid the use of size_t in the partitioner. - Use `Span` instead of `Elem` where `node_id` is not needed. - Remove the `const_cast`. - Make sure the constness is not removed in the `Elem` by making it reference only. size_t is implementation-defined, which causes issue when we want to pass pointer or span.
eXtreme Gradient Boosting
Community | Documentation | Resources | Contributors | Release Notes
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 (Kubernetes, Hadoop, SGE, Dask, Spark, PySpark) and can solve problems beyond billions of examples.
