Embedding-based Retrieval with Two-Tower Models in Spotlight

At Snap, we want to empower you to learn about the world and have fun with other Snapchatters. On Spotlight, Snap’s short-video platform, we personalize what you see based on your interests and previous watch history. This blog discusses the challenges we faced and techniques we applied for large-scale embedding-based retrieval, which selects the stories that users may like from a large candidate pool in real time.
