Binary Classification Binary Classification
===================== =====================
This is the quick start tutorial for xgboost CLI version. This is the quick start tutorial for xgboost CLI version.
Here we demonstrate how to use XGBoost for a binary classification task. Before getting started, make sure you compile xgboost in the root directory of the project by typing ```make``` Here we demonstrate how to use XGBoost for a binary classification task.
