Webb12 apr. 2024 · Based on the cooperative game theory, SHAP can interpret a variety of ML models and produce visual graphical results. The SHAP method reflects the effects of features on the final predictions by calculating the marginal contribution of features to the model, namely SHAP values. WebbThe goal of SHAP is to explain a machine learning model’s prediction by calculating the contribution of each feature to the prediction. The technical explanation is that it does this by computing Shapley values from coalitional game theory. Of course, if you’re unfamiliar with game theory and data science, that may not mean much to you.
