title: Interpret xgboost model tree image leaf = -0.1
body: <p>I'm trying to visualize my xgboost model using python plot_tree method. The first few trees end up with a picture showing leaf = -0.1, while some other the rest seem fine. How do I interpret this? Does this mean I use more trees than needed?</p>
