WebbAbstract. Shapley value is a popular approach for measuring the influence of individual features. While Shapley feature attribution is built upon desiderata from game theory, some of its constraints may be less natural in certain machine learning settings, leading to unintuitive model interpretation. In particular, the Shapley value uses the ...WebbShapley value is the derivation of the applied cost and gained profit—distributed equally among the players—based on individual contribution. In machine learning, Shapley …

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.

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.
