Scoring at Scale: Generating Follow Recommendations for Over 690 Million LinkedIn MembersSummit 2020

The Communities AI team at LinkedIn generates follow recommendations from a large (10's of millions) set of entities to each of our 690+ million members. These recommendations are driven by ML models that rely on three sets of features (member, entity, and interaction features). In order to support a fast-growing user base, an expanding set of recommendable entities (members, companies, hashtags, groups, newsletters etc.) and more sophisticated modeling approaches, we have re-engineered the system to allow for efficient offline scoring in Spark. In particular, we have handled the 'explosive' growth of data by developing a 2D Hash-Partitioned Join algorithm that optimizes the join of hundreds of terabytes of features without requiring significant data shuffling. In addition to a 5X runtime performance gain, this opened the opportunity for training and scoring with a suite of non-linear models like XGBoost, which improved the global follow rate on the platform by 15% and downstream engagement on LinkedIn feed from followed entities by 10%.
