ICE (Individual Conditional Expectation)
Individual Conditional Expectation plots the model's predictions for each observation by varying a specific feature, revealing the heterogeneity of effects that PDP can mask. This method shows how predictions change for each instance individually.
Decision Tree Surrogate
A decision tree surrogate is an interpretable model trained to approximate the predictions of a complex model, offering an easy-to-visualize logical structure. It captures the global decision rules of the original model in the form of hierarchical branches.
Global Counterfactual Explanations
Global counterfactual explanations identify the minimal changes in features that would systematically change the model's predictions for different classes. They reveal the global decision boundaries and critical thresholds of the model.
