TL;DR
This paper introduces PCDF, a parallel-distributed framework for sponsored search advertising that reduces inference latency and supports end-to-end online training of complex CTR models.
Contribution
It proposes a novel parallel-computing framework that splits computation into three parts for efficient online deployment and training of CTR models in sponsored search.
Findings
Reduces overall inference latency significantly.
Supports end-to-end offline training and online deployment.
First to enable end-to-end online training for complex CTR models in this context.
Abstract
Traditional online advertising systems for sponsored search follow a cascade paradigm with retrieval, pre-ranking,ranking, respectively. Constrained by strict requirements on online inference efficiency, it tend to be difficult to deploy useful but computationally intensive modules in the ranking stage. Moreover, ranking models currently used in the industry assume the user click only relies on the advertisements itself, which results in the ranking stage overlooking the impact of organic search results on the predicted advertisements (ads). In this work, we propose a novel framework PCDF(Parallel-Computing Distributed Framework), allowing to split the computation cost into three parts and to deploy them in the pre-module in parallel with the retrieval stage, the middle-module for ranking ads, and the post-module for re-ranking ads with external items. Our PCDF effectively reduces the…
