GeneralizedDelayedFeedbackModel withPost-Click InformationinRecommenderSystems

However,accurate conversion labels arerevealed after along delay,which harms the timeliness ofrecommender systems. Previousliterature concentrates onutilizing early conversions to mitigate such a delayed feedback problem. In this paper, we show that post-click user behaviors are also informative to conversion rate prediction and can beused toimprovetimeliness.
