Grow-and-prune strategies are heuristic algorithms designed for efficient discovery of group counterfactual explanations in recommender systems. They aim to balance the cost of explanation generation with the quality, conciseness, and fairness of the explanations provided to groups.
Grow-and-prune strategies are smart algorithms that help explain why a group of people received a certain recommendation, like a movie suggestion. They work by efficiently finding out what past actions, if removed, would change the recommendation, balancing how good and fair the explanation is against the effort to create it.
