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. 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 …

Webb25 nov. 2024 · Now, if we talk in terms of Game Theory, the “game” here is the prediction task for a single instance of the dataset. The “players” are the feature values of the instance that collaborate to play the game (predict a value) similar to the meal example where Pranav, Ram, and Abhiraj went for a meal together. WebbGame theory experienced a flurry of activity in the 1950s, during which the concepts of the core, the extensive form game, fictitious play, repeated games, and the Shapley value were developed. The 1950s also saw the first applications of game theory to philosophy and political science .
