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.

The Shapley value is a solution concept in cooperative game theory. It was named in honor of Lloyd Shapley, who introduced it in 1951 and won the Nobel Memorial Prize in Economic Sciences for it in 2012.
