WebbThe main idea behind SHAP values is to decompose, in a fair way, a prediction into additive contributions of each feature. Typical visualizations include waterfall plots and force plots: sv_waterfall(shp, row_id = 1L) + theme(axis.text = element_text(size = 11)) Works pretty sweet, and factor input is respected! Webb12 apr. 2024 · The SHAP method reflects the effects of features on the final predictions by calculating the marginal contribution of features to the model, namely SHAP values. The positive and negative of SHAP values respectively represent increasing and decreasing effects on the target predictions. On the other hand, the average of absolute SHAP …
