Optimizing Multi-Hop Document Retrieval Through Intermediate Representations (2025.findings-acl)
Copied to clipboard
| Challenge: | Existing approaches to addressing multi-hop queries are computationally expensive . despite their success, large language models often generate factually incorrect answers . |
| Approach: | They propose a layer-by-layer reasoning approach that leverages intermediate representations from the middle layers to retrieve external knowledge. |
| Outcome: | The proposed method outperforms existing RAG methods on open-domain multi-hop question-answering datasets while maintaining inference overhead similar to that of standard RAG. |
