Model merging enhances conversational search without retraining · 2 sources tracked

Researchers have introduced a novel training-free strategy for improving conversational information retrieval by merging existing models. This approach, which utilizes techniques like Model Soup and Slerp, aims to create a single retrieval model capable of operating effectively in both ad-hoc and conversational settings without requiring further fine-tuning. Experiments show that this model merging significantly boosts ad-hoc search capabilities for conversational retrievers, leading to up to a 15% improvement in NDCG@3 under zero-shot conditions and enhancing generalizability across different datasets.
