PinnerSage creates multi-modal user embeddings for better Pinterest recommendations.

problem Single high-dimensional embeddings fail to fully understand user interests.
method Hierarchical clustering and Medoids to summarize user actions into coherent clusters.
result PinnerSage outperforms single embedding methods in personalized recommendations.

Recent advancements in deep neural networks for graph-structured data have led to state-of-the-art performance on recommender system benchmarks. However, making these methods practical and scalable to web-scale recommendation tasks with billions of items and hundreds of millions of users remains a challenge. Here we de…

Two-stage recommender systems show better performance when components interact rather than operate independently.

problem Two-stage recommender systems are often treated as sums of their parts, ignoring interactions between components.
method Used synthetic and real-world data to demonstrate interactions between ranker and nominators. Derived a generalization lower bound and proposed a Mixture-of-Experts approach to learn optimal item pools.
result Independent nominator training can lead to performance on par with random recommendations, highlighting the importance of interactions.

RNE tackles scalable recommendation for billion-scale scenarios.

problem Designing a scalable recommendation system for diverse and dynamic user interests.
method RNE uses a diversity- and dynamics-aware neighbor sampling method for scalable network embedding.
result RNE achieves high-quality and diverse results on a billion-scale user-item graph.
