Webb27 dec. 2024 · Now, we have SHAP values for every sample, instead of just samples in one test split of the data, and we can plot these easily using the SHAP library. We first just have to update the index of X to match the order in which they appear in each test set of each fold, otherwise, the color-coded feature values will be all wrong. Notice that we re-order X … Webb20 mars 2024 · 1 Answer.

WebbCreate a SHAP dependence scatter plot, colored by an interaction feature. Plots the value of the feature on the x-axis and the SHAP value of the same feature on the y-axis. This shows how the model depends on the given feature, and is like a richer extenstion of classical parital dependence plots.
