Explainable AI with Shapley values — SHAP latest documentation

WebbSHAP (SHapley Additive exPlanations) is one of the most popular frameworks that aims at providing explainability of machine learning algorithms. SHAP takes a game-theory-inspired approach to explain the prediction of a machine learning model. WebbReading SHAP values from partial dependence plots¶. The core idea behind Shapley value based explanations of machine learning models is to use fair allocation results from cooperative game theory to allocate credit for a model’s output \(f(x)\) among its input features . In order to connect game theory with machine learning models it is nessecary … Webb26 sep. 2024 · Red colour indicates high feature impact and blue colour indicates low feature impact.
