Webb我们提出了一种新的训练程序,给定适当的KG,提高基于部分的分类器的可解释性。它是基于Shapley值(SHAP),它输出各个部分元素的特征属性,以最终分类,我们将其与KG进行比较。我们使用SHAP信息来加权训练时反向传播的损失。 专家知识信息用KG进行编码。 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. By interpreting a model trained on a set of features … Visa mer Business example Consider a simplified description of a business. An owner, o, provides crucial capital in the sense that, without him/her, no gains can be obtained. There are m workers w1,...,wm, each of whom contributes an … Visa mer In their 1974 book, Lloyd Shapley and Robert Aumann extended the concept of the Shapley value to infinite games (defined with respect … Visa mer The Shapley value $${\displaystyle \varphi _{i}(v)}$$ was decomposed in into a matrix of values Each value Visa mer
