Researchers have developed a score-only distillation method to create compact dense retrieval models. This technique allows a smaller student model to learn ranking behavior from a larger teacher model by only using score vectors, without needing access to the teacher's internal states. The distilled models can achieve up to 50% of the performance gap between the base and teacher models, offering significant speed improvements for query and document encoding. AI
IMPACT Enables more efficient deployment of large retrieval models by creating smaller, faster versions.
