Generator and Critic: A Deep Reinforcement Learning Approach for Slate Re-ranking in E-commerce
[article]
2020
arXiv
pre-print
Preserved Fulltext
In this paper, we present a novel Generator and Critic slate re-ranking approach, where the Critic evaluates the slate and the Generator ranks the items by the reinforcement learning approach. ...
The Generator and Critic approach improves both the slate efficiency(4% gmv and 5% number of orders) and diversity in live experiments on one of the largest e-commerce websites in the world. ...
PRELIMINARY In this section we introduce the basic concepts of slate re-ranking in e-commerce, and reinforcement learning. ...

Experiments on public datasets and real-world data from e-commerce datasets show that CSSO outperforms popular comparable ranking methods in terms of adherence to distributional criteria while producing ...
We introduce conditional sequential slate optimization (CSSO), which jointly learns to optimize for traditional ranking metrics as well as prescribed distribution criteria of documents within the slate ...
However, these methods mostly focus on the ranking quality of the slate but lack a distributional objective, which is critical in many real world and specifically e-commerce applications. ...
