Idea
Fast SHAP computation platform accelerating decision tree interpretability for large-scale enterprise data.
Research Paper
Core Innovation
This paper introduces WOODELF, a novel SHAP algorithm that integrates decision trees, game theory, and Boolean logic into a unified framework. It constructs pseudo-Boolean formulas to represent feature values and tree structures, enabling linear-time computation of Background SHAP and other interaction values on both CPU and GPU without custom low-level code.
Why It Matters
Interpreting decision tree models is critical in regulated and high-stakes industries like finance and medicine. WOODELF drastically reduces computation time for SHAP values, enabling real-time, large-scale explainability workflows. This efficiency gain supports broader adoption of transparent AI and improves trust and compliance at scale.
