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: The function Visa mer The Shapley value has many desirable properties. Efficiency The sum of the … Visa mer The Shapley value $${\displaystyle \varphi _{i}(v)}$$ was decomposed in into a matrix of values 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 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 Webb26 juli 2024 · Sharply Value Plot Prediction on Test Dataset After model training, the next step is to check how your tuned model performing on an unseen or test dataset. You can evaluate the model on test data using predict_model ( ) function. The tuned_xgboost contained the 20% data split which inherited during the data pre-processing step.

WebbShapley value decomposition. 夏普利值分解法基于传统回归方程分解与夏普利值法相结合，可把目标变量的不平等分解为其决定因素的贡献，并量化分为各回归变量对因变量不平等的贡献。 该方法的原理为运用合作博弈的思想来分解各个回归变量对因变量差异的贡献。 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.
