Counterfactually Evaluating Explanations in Recommender Systems

Abstract: Modern recommender systems face an increasing need to explain their recommendations. Despite considerable progress in this area, evaluating the quality of explanations remains a significant challenge for researchers and practitioners. Prior work mainly conducts human study to evaluate explanation quality, which is usually expensive, time-consuming, and prone to human bias. In this paper, we propose an offline evaluation method that can be computed without human involvement. To evaluate an explanation, our meth… Show more

“…Another area where MU may be important for RS is in the development of more transparent and fair models [217]. MU can help to improve the interpretability and explainability of RS [218]. Unlearning can help to make these models more transparent by allowing them to remove irrelevant or misleading features and focus on the most important factors for making accurate recommendations [219].…”
