Generating and Understanding Personalized Explanations in Hybrid Recommender Systems

Abstract: Recommender systems are ubiquitous and shape the way users access information and make decisions. As these systems become more complex, there is a growing need for transparency and interpretability. In this article, we study the problem of generating and visualizing personalized explanations for recommender systems that incorporate signals from many different data sources. We use a flexible, extendable probabilistic programming approach and show how we can generate real-time personalized recommendations. We th… Show more

“…In Reference 60, Zhang et al generate explanations as to “why” or “why not” an item is not recommended and consequently proposed a framework that does not recommend an item that the system considers not worth buying, thus gaining the user's trust and helping the user to take a more informed purchasing decision. The recent study 61 proposes the evaluation of the effects of explanations on user preferences. The authors studied personalized recommendations and explanations for real users on a music platform.…”

“…When there are multiple categories of items or an underlying context for recommending items to the users, we can form multiple user content baskets or introduce attention [30] for accurate and explainable recommendations [17]. Lastly, our framework can also be adapted to similar recommendationrelated tasks that have reasons to restrict access to personal user info, e.g.…”
