Shap summary plot explanation

Webb5 okt. 2024 · SHAP is an acronym for SHapley Additive Explanations. It is one of the most commonly used post-hoc explainability techniques. SHAP leverages the concept of cooperative game theory to break down a prediction to measure the impact of each feature on the prediction.
