The Tool for System Evolution—AB Testing Platform

The previous chapters have introduced the technology and application of recommender systems. The author believes that the subtlety of ranking, the richness of recall, the comprehensiveness of portraits, the embedded thinking of content understanding, the balance of re-ranking, etc., have all left a deep impression on the readers. However, the designers and users of recommender systems also need a mature and sophisticated system for evaluating and indicating recommender systems to guide the evolution of recommender system technology, which is the protagonist of this chapter—the AB testing platform.
