custom base values for tree explainer #2934

Open nshahpazov opened 1 year ago

nshahpazov commented 1 year ago

Is there a way to set the base_values before calculating the shap values for a TreeExplainer in the shap package? I'm using a gpu xgbooster and I want to be able to set the base values.

Thanks in advance!

The base values for shap are set as the average model output. Why do you want to set this value manually?
