Webb24 nov. 2024 · Shapley values are often used to find the most important features for a model. The selection is made after observing the explanation, and the number of variables to retain is often arbitrary. To … 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 … 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: $${\displaystyle v\colon 2^{N}\to \mathbb {R} }$$, … Visa mer Business example Consider a simplified description of a business.

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 In their 1974 book, Lloyd Shapley and Robert Aumann extended the concept of the Shapley value to infinite games (defined with respect to a non-atomic measure), creating the diagonal formula. This was later extended by Jean-François Mertens Visa mer The Shapley value provides a principled way to explain the predictions of nonlinear models common in the field of machine learning. By interpreting a model trained on a set of features … Visa mer
