When plotting a tree from catboost, it shows val in leaves; what do these values represent?
I can't find the answer in their official tutorial on plotting, nor are there any such questions answered anywhere that I could find. Like:
- LightGBM plot_tree() Leaf numbers
- What' the meaning of "Val" in the visualization of a lightgbm tree?
- https://github.com/catboost/catboost/issues?q=plot_tree
