SHAP & Game Theory For Recommendation Systems

Download Slides

Shap for recommendation systems: How to use existing Machine Learning models as a recommendation system. We introduce a game-theoretic approach to the study of recommendation systems with strategic content providers. Such systems should be fair and stable. Showing that traditional approaches fail to satisfy these requirements, we propose the Shapley mediator. We show that the Shapley mediator fulfills the fairness and stability requirements, runs in linear time, and is the only economically efficient mechanism satisfying these properties.
