新方法量化树模型中Shapley值的鲁棒性

研究人员开发了一种使用不精确狄利克雷模型(IDM)的新方法,用于分析决策树和随机森林中Shapley值的鲁棒性。该方法在将未标记实例引入树叶时,量化和检查区间值Shapley值。该方法允许基于悲观和平均原则计算这些区间值Shapley值,并且可以扩展到Banzhaf值。实验证明了这些区间值Shapley值的行为及其在消除无信息特征偏差方面的效用。 AI

影响 增强了对常见机器学习模型中特征归因鲁棒性的理解。

    区间值SHAP在基于树的模型中的应用

    arXiv:2610.11953v1 Announce Type: new Abstract: Shapley values are among the most popular feature-attribution explanations. Efficient approaches for computing/estimating Shapley values for tree-based models, which are state-of-the-art for tabular data sets, have been developed. H…
