WebbShapley values tell us how to fairly distribute the “payout” (= the prediction) among the features. A player can be an individual feature value, e.g. for tabular data. A player can also be a group of feature values. For example to explain an image, pixels can be grouped to superpixels and the prediction distributed among them.

Webb24 juni 2024 · このブログでは、AI モデルの透明性に関する基本的な概念と手法を説明しましたが、 他にも、Sharply Valueを近似的に算出するSHAP、Impurity-based feature importance、頻度ベースの特徴量重要度（frequency-based feature importance、勾配ブースティング向け）など、多くの手法があります。 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.
