Abstract

Recommendations at Scale

Behavioral retargeting consists of displaying online advertisements that are personalized according to each user’s browsing history. At this point, the selection of the products to display in the banner needs to be fast and accurate. At Criteo, we built a recommender system which is able to choose a dozen of relevant products from over two billion products in a few milliseconds. In this talk, we will expose the problems we faced whilst building this system and how we solved them thanks to a mix of online and offline computations.

Olivier Toromanoff

Olivier is based in Paris and he is  fluent in French, English, Dutch and German.

 

Abstract

Prediction @ Criteo: learning at scale on Hadoop

Machine Learning is at the heart of the Criteo platform : Sourcing the inventory and generating the banners for 2 billion daily displays require 15 million predictions per second. In this talk, we will present the infrastructure that allow us to train and deploy 1700 models a day as well as the tooling we set up to continuously monitor and improve this pipeline.
