Shap values game theory
Webb2 Game theory and SHAP (Shapley additive explanation) values From a game theory perspective, a modelling exercise may be rationalised as the superposition of multiple collaborative games where, in each game, agents (explanatory variables) strategically interact to achieve a goal – making a prediction for a single observation. WebbShapley Values. A prediction can be explained by assuming that each feature value of the instance is a “player” in a game where the prediction is the payout. Shapley values – a …

WebbSHAP Values - Interpret Predictions Of ML Models using Game-Theoretic Approach ¶ Machine learning models are commonly getting used to solving many problems nowadays and it has become quite important to understand the performance of these models. WebbWelcome to the SHAP Documentation¶. SHAP (SHapley Additive exPlanations) is a game theoretic approach to explain the output of any machine learning model. It connects optimal credit allocation with local explanations using the classic Shapley values from game theory and their related extensions (see papers for details and citations.
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. Webb20 nov. 2024 · As mentioned above, Shapley values are based on classic game theory. There are many game types such as cooperative/non-cooperative, symmetric/non-symmetric, zero-sum/non zero-sum etc. But Shapley values are based on the cooperative (coalition) game theory. In coalition game theory, a group of players comes together to …
