What techniques can improve the interpretability of complex models?
Asked on Feb 22, 2026
Answer
Improving the interpretability of complex models is crucial for understanding model decisions and gaining trust in machine learning applications. Techniques such as feature importance, SHAP values, and LIME are commonly used to make complex models more interpretable by providing insights into how features influence predictions.
Example Concept: SHAP (SHapley Additive exPlanations) values are a popular method for interpreting complex models. They provide a unified measure of feature importance by assigning each feature an importance value for a particular prediction. SHAP values are based on cooperative game theory and offer a consistent way to attribute the output of a model to its input features, making them useful for understanding individual predictions and overall model behavior.
Additional Comment:
- Feature importance can be derived from tree-based models like Random Forests and Gradient Boosting.
- LIME (Local Interpretable Model-agnostic Explanations) approximates complex models locally with interpretable models to explain individual predictions.
- Partial dependence plots visualize the relationship between a feature and the predicted outcome, holding other features constant.
- Global surrogate models are simpler models trained to approximate the predictions of complex models, offering a holistic view of model behavior.
