ReuseGR system improves generative retrieval efficiency and personalization

By PulseAugur Editorial · [1 sources] ·

Researchers have developed ReuseGR, a novel generative retrieval system designed to improve efficiency and personalization. The system decouples offline query planning from online personalized completion, allowing a smaller model to reuse computation from a larger model across similar requests. This approach significantly reduces latency while maintaining or improving retrieval quality and user engagement metrics, as demonstrated in offline experiments and a user-level A/B test. AI

IMPACT This system's approach to decoupling and reusing computation could significantly reduce serving costs for large generative models in retrieval applications.

    ReuseGR: Offline--Online Decoupled Generative Retrieval via Adaptive Prefix Reuse

    Larger generative retrieval models can improve retrieval quality, but their decoding cost makes low-latency serving difficult. When different users submit the same query, generating complete Semantic IDs (SIDs) for every request repeats computation, while their interaction histor…
