RLTP: Reinforcement Learning to Pace for Delayed Impression Modeling in Preloaded Ads

no code implementations6 Feb 2023 Penghui Wei, Yongqiang Chen, Shaoguo Liu, Liang Wang, Bo Zheng

In a whole delivery period, advertisers usually desire a certain impression count for the ads, and they also expect that the delivery performance is as good as possible (e. g., obtaining high click-through rate).
