Title: WITHDRAWN: Stacked Models and the Explainability Tradeoff in Recommender Systems
Author(s): shaudi mahdavi hosseini

Keywords: explainability; recommender systems

Recommender systems often involve a series stacked models, complicating attempts at explainability that do not compromise accuracy metrics, particularly as systems increasingly grow complex. In this work we explore the applicability of the best-known explainability techniques to stylized recommender systems in the healthcare information search domain. We use a theoretical derivation to capture a explainability and accuracy tradeoff, and show conditions when this tradeoff attenuates in the proposed stylized setting.
