SHAP Model Interpretability FAQs

Question 1

How do I choose the right SHAP explainer?

Accepted Answer

The skill provides a selection logic: use TreeExplainer for trees, DeepExplainer for neural networks, LinearExplainer for linear models, or the generic shap.Explainer for automatic selection.

Question 2

What kind of visualizations can I generate?

Accepted Answer

You can create beeswarm and bar plots for global importance, waterfall and force plots for individual predictions, and scatter plots for feature interactions.

Question 3

Which ML models are supported by the SHAP skill?

Accepted Answer

It supports all major model types, including tree-based models like XGBoost and Random Forest, deep learning frameworks like PyTorch and TensorFlow, linear models, and black-box models.

Question 4

Can I use SHAP for model debugging?

Accepted Answer

Yes, it includes specialized workflows to identify prediction errors, detect data leakage through unexpected importance, and validate feature relationships.

Question 5

How do I optimize SHAP for large datasets?

Accepted Answer

The skill suggests using representative background data (via kmeans or sampling), batching computations, and selecting specialized explainers over the slower KernelExplainer.
