A Hybrid Bandit Model with Visual Priors for Creative Ranking in Display Advertising
The previous article Dynamic Creative Optimization in Online Display Advertising mentioned that creative optimization can generally be divided into three main parts: creative generation, creative selection, and creative delivery. This article mainly covers some approaches for creative selection, which typically involves an exploration-exploitation (E&E) process.
This article is primarily based on a paper published by Alibaba: A Hybrid Bandit Model with Visual Priors for Creative Ranking in Display Advertising. The paper achieves the goal of ranking candidate creatives under the same campaign (i.e., creative selection) through list-wise training. List-wise can be considered as the exploitation part, while the paper also uses a bandit model for exploration. The overall approach is quite reasonable and has been validated in real-world industry scenarios, making it worth reading.
