Challenges in Deploying Large Neural Rankers
The deployment of multi-billion parameter neural rankers in real-world systems poses a significant challenge in information retrieval (IR). These advanced neural rankers demonstrate high effectiveness but are hampered by their substantial computational requirements for inference, making them impractical for production use. It is necessary to balance the benefits of these large models with their operational feasibility.
Research Efforts and Practical Advancements
Significant research efforts have been made in the field to address these challenges. Practical advancements include:
- Utilization of synthetic text from large language models for knowledge transfer to smaller models
- Multi-step reasoning and code distillation for click-through-rate prediction
- Distillation of cross-attention scores and self-attention modules of transformers
- Utilizing pseudo-labels for generating synthetic data for domain adaptation
- Proposed method called InRanker for distilling large neural rankers into smaller, more effective versions
Practical Implementation of InRanker
The InRanker method involves two distillation phases, utilizing real-world data and synthetic queries generated by a large language model. The research has successfully demonstrated that smaller models, distilled using the InRanker methodology, significantly improved their effectiveness in out-of-domain scenarios, providing a more practical and scalable solution for IR tasks.
Implications and Future Applications
This research presents a practical solution to the challenge of using large neural rankers in production environments. The InRanker method effectively distills the knowledge of large models into smaller, more efficient versions without compromising out-of-domain effectiveness. This approach addresses the computational constraints of deploying large models and opens new avenues for scalable and efficient IR.
