Beyond the Click-Through Rate: Web Link Selection with Multi-level Feedback

no code implementations4 May 2018 Kun Chen, Kechao Cai, Longbo Huang, John C. S. Lui

The web link selection problem is to select a small subset of web links from a large web link pool, and to place the selected links on a web page that can only accommodate a limited number of links, e. g., advertisements, recommendations, or news feeds.

Multi-level Feedback Web Links Selection Problem: Learning and Optimization

no code implementations8 Sep 2017 Kechao Cai, Kun Chen, Longbo Huang, John C. S. Lui

To our best knowledge, we are the first to model the links selection problem as a constrained multi-armed bandit problem and design an effective links selection algorithm by learning the links' multi-level structure with provable \emph{sub-linear} regret and violation bounds.
