Abstrakt: The article focuses on enhancing recommender systems by addressing the challenges of mixed causal and non-causal associations in user feedback. Topics include the proposal of a model-agnostic causal learning framework called IV4Rec that uses search queries as instrumental variables, the decomposition of embedding vectors into causal and non-causal parts, and the improvement of recommendation system performance through this approach.
