Webb23 juni 2024 · What is SHAP? A couple of years ago, the concept of Shapely values from game theory from the 1950ies was discovered e.g. by Scott Lundberg as an interesting approach to explain predictions of ML models. The basic idea is to decompose a prediction in a fair way into additive contributions of features. Webb这是一个相对较旧的帖子,带有相对较旧的答案,因此我想提供另一个建议,以使用 SHAP 确定特征对Keras模型的重要性.
