Introduction to the Shapley value 来自 EconPapers 喜欢 0 阅读量: 72 作者: AE Roth 摘要: Composed in honour of the sixty-fifth birthday of Lloyd Shapley, this volume makes accessible the large body of work that has grown out of Shapley's seminal 1953 paper. Each of the twenty essays ...
SHAP (SHapley Additive exPlanations) values are a way to explain the output of any machine learning model. It uses a game theoretic approach that measures each player's contribution to the final outcome. In machine learning, each feature is assigned an importance value representing its contribution...
Shapley values The Shapley value is a mathematical concept in game theory that was introduced by Lloyd Shapley in 1951. He was later awarded the Nobel Prize in Economics for this work. Suppose that we have a cooperative game with M players numbered from 1 to M, and let F denote t...
答案在12.2.1 "The Shapley value"小节。 沙普利值的计算是通过分析每个玩家对合作游戏中所有可能联盟的边际贡献来完成的。具体来说,它考虑了每个玩家加入不同联盟时对总收益的增加量。沙普利值通过平均所有可能的联盟顺序下玩家的边际贡献来计算每个玩家应得的份额。 计算公式涉及到对每个可能的玩家排列进行分析,计算...
The original values from the input data are replaced by its SHAP values. However it is not the same replacement for all the columns. Maybe a value of 10 purchases is replaced by the value 0.3 in customer 1, but in customer 2 it is replaced by 0.6. This change is due to how the...

以下方法解释了模型的整体行为:局部依赖图,累积的局部效应,特征交互,特征重要性,全局代理模型andPrototypes and Criticisms. 为了解释单个预测,我们有局部代理模型,Shapley值解释,反事实解释(以及紧密相关的:(对抗性示例)).一些方法可以用来解释全局模型行为和个体预测的两个方面:个体条件期望和影响实例....
There are several techniques to reduce the number of features, popular ones being merely dropping some features according to a rule such as univariate analysis (i.e., correlation with the targety) or to an importance score (p-value, feature importance from tree-based algorithms, Shapley values...
Thus development of game theory is closely related to the economic development. In recent years, the research on the non-differentiability of Shapley value posed by Belgian Mertens is one of the advanced studies in game theory.ShengkaiDalianZhang...
