The Shapley value not only has desirable properties, it is also the only payment rule satisfying some subset of these properties. For example, it is the only payment rule satisfying the four properties of Efficiency, Symmetry, Linearity and Null player. See for more characterizations. Visa mer 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 Visa mer Formally, a coalitional game is defined as: There is a set N (of n players) and a function $${\displaystyle v}$$ that maps subsets of players to the real numbers: $${\displaystyle v\colon 2^{N}\to \mathbb {R} }$$, with $${\displaystyle v(\emptyset )=0}$$, … Visa mer The Shapley value has many desirable properties. Efficiency The sum of the Shapley values of all agents equals the value of the grand coalition, so that all the gain is distributed among the agents: Visa mer The Shapley value provides a principled way to explain the predictions of nonlinear models common in the field of machine learning.
