Webb11 jan. 2024 · Shapley Values in Python In 2024, Lundberg and Lee published a paper titled A Unified Approach to Interpreting Model Predictions. They combined Shapley values with several other model explanation methods to create SHAP values (SHapley Additive exPlanations) and the corresponding shap library. WebbWe propose a novel definition of Shapley values with uncertain value functions based on first principles using probability theory. Such uncertain value functions can arise in the context of explainable machine learning as a result of non-deterministic algorithms. holiday inn express keene new hampshire
