SetMIR tackles multi-interest retrieval as set prediction, boosting Snap's ad performance

Researchers have developed SetMIR, a novel approach to multi-interest retrieval that frames the problem as a set prediction task. This method utilizes a transformer to encode user history and K learnable queries to decode distinct user interests, each with a presence score. SetMIR addresses issues like interest collapse and static dispatch by employing Hungarian matching during training and presence scores with Non-Maximum Suppression (NMS) at serving time to optimize query issuance. When tested on Snap's Dynamic Product Ads data, SetMIR surpassed existing multi-interest retrievers in performance while reducing ANN queries by 33%. Its deployment in Snap's DPA production stack resulted in a 3.1% increase in overall CVR and significant lifts in CTR and CVR for a specific retrieval source. AI

IMPACT This new retrieval method could enhance personalization and efficiency in recommender systems and ad platforms.

    SetMIR: Multi-Interest Retrieval as Set Prediction

    Embedding-based retrieval is at the core of industrial recommender systems, but a single user embedding is often too limited to capture a user's diverse interests. Multi-interest retrieval addresses this by using multiple user embeddings, yet existing methods still suffer from tw…
