Shapley analysis
Webb2 maj 2024 · Hence, SHAP analysis revealed intrinsic differences in model anatomy for comparably accurate predictions. In order to compare feature importance in closely related molecules, SHAP analysis was also applied to compounds from the same analog series (structural analogs). Three analogs from the same series were present in the test set.

Webb3 jan. 2024 · Computing Shapley values for tree-based model. The method in the previous subsection was presented for pedagogical purposes only. In reality, the need to build n factorial models is prohibitive. For even 5 features, we need to train no less than 5!=120 models, and this as many times as there are predictions to analyze. Webb10 apr. 2024 · Shapley values are designed to attribute the difference between a model's prediction and an average baseline to the different predictor variables used as inputs to the model. Because of its ease of interpretation, the Shapley approach has quickly become one of the most popular model-agnostic methods within explainable artificial intelligence …

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.
