A data scientist is using SHAP to explain a complex ensemble model's predictions. A business stakeholder asks why a particular prediction was made. The data scientist wants to show the most influential features for that single prediction. Which SHAP visualisation is most appropriate?
Trap 1: A SHAP summary plot showing mean absolute SHAP values across all…
Summary plots show global feature importance, not the explanation for a specific prediction.
Trap 2: A SHAP dependence plot for the top feature
Dependence plots show how a feature's value affects predictions across the dataset, not a single instance.
Trap 3: A SHAP bar chart of absolute feature importance
Bar charts show global importance but do not indicate direction or magnitude for a specific instance.
- A
A SHAP summary plot showing mean absolute SHAP values across all features
Why wrong: Summary plots show global feature importance, not the explanation for a specific prediction.
- B
A SHAP dependence plot for the top feature
Why wrong: Dependence plots show how a feature's value affects predictions across the dataset, not a single instance.
- C
A SHAP bar chart of absolute feature importance
Why wrong: Bar charts show global importance but do not indicate direction or magnitude for a specific instance.
- D
A SHAP force plot for the individual prediction
Force plots display the contribution of each feature to a single prediction, ideal for local explanations.
