Exact computation of Shapley R-squared in polynomial time

## Q-SHAP: Feature-Specific $R^2$ Values for Tree Ensembles This package is used to compute feature-specific $R^2$ values, following Shapley decomposition of the total $R^2$, for tree ensembles in polynomial time.

This version only takes output from XGBoost, scikit-learn Decision Tree, and scikit-learn GBDT. We are working to update it for random forest in the next version. Please check Q-SHAP Tutorial.ipynb for more usage.
