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. 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. To each cooperative game it assigns a unique distribution (among the players) of a total surplus generated by the coalition of all players.
