Shapley2命令

Webb在SHAP被广泛使用之前,我们通常用feature importance或者partial dependence plot来解释xgboost。. feature importance是用来衡量数据集中每个特征的重要性。. 简单来说,每个特征对于提升整个模型的预测能力的贡献程度就是特征的重要性。. (拓展阅读: 随机森林 … WebbAbstract. This program performs (exact additive) decomposition of a sample statistic by effects specified in factor list. To perform the Shapley decomposition, the effects are eliminated one by one, and marginal effects from each exclusion are weighted in such a way that all exclusion trajectories have equal weights.
