Webb3 sep. 2024 · Display the cumulative effect of interactions. Decision plots support SHAP interaction values: the first-order interactions estimated from tree-based models. In contrast to a dependence plot that shows a single interaction for many predictions, a decision plot displays all main effects and interactions together. Webb28 jan. 2024 · SHAP uses the game theoretic approach of Shapely values that ensures the contributions of the inputs sum to the predicted output plus a baseline . SHAP is an attractive option because it can dissect interactions between inputs, for example when inputs are correlated. SHAP is also beneficial in that it can be used with any arbitrary …

WebbSHAP feature dependence might be the simplest global interpretation plot: 1) Pick a feature. 2) For each data instance, plot a point with the feature value on the x-axis and the corresponding Shapley value on the y-axis. 3) … WebbCreate a heatmap plot of a set of SHAP values. This plot is designed to show the population substructure of a dataset using supervised clustering and a heatmap. …
WebbThe SHAP interaction value indicates the contribution of the joint action of two different variables to the prediction results, which shows the interaction effect of the two variables. The SHAP interaction value is calculated by Equations (14), (15). (14) ϕ i, j = ∑ S ⊆ N \ {i, j} S! M-S-2! 2 M-1! δ ij S. When i ≠ j, and (15) δ ij S ...
