qshap: Fast Calculation of Feature Contributions in Boosting Trees
Computes feature-specific R-squared (R2) contributions for
boosting tree models using a Shapley-value-based decomposition of the
total R-squared in polynomial time. Supports models fitted with
'XGBoost' and 'LightGBM', and provides efficient parallel
implementations suitable for large-scale problems. Multiple
visualization tools are included for interpreting and communicating
feature contributions. The methodology is described in Jiang, Zhang,
and Zhang (2025) <doi:10.48550/arXiv.2407.03515>.
