Large-Scale Real-Time Product Recommendation At Criteo

by Romain Lerallut (Criteo)

Performance retargeting consists of displaying online advertisements that are personalized according to each user’s browsing history. Criteo’s recommender system chooses a dozen relevant products from over two billion candidates in a few milliseconds, not only for their click performance but also for their probability to generate a sale. In this talk, we will expose how to build such a system through a combination of offline and real-time computations, and the challenges of evolving it when regular A/B testing no longer suffices.
