Описание тега xgboost
XGBoost is a library for constructing boosted tree models in R, Python, Java, Scala, and C++. Use this tag for issues specific to the package (i.e. input/output, installation, functionality).
Before using the XGBoost tag, try to test whether your issue is related specifically to the functionality of XGBoost. Often, problems arise from the surrounding model-building environment (such as R's caret or Python's scikit-learn), the quality of the data being used, or purely statistical concerns that might belong on Cross Validated.
