Mix-of-Granularity: Optimize the Chunking Granularity for Retrieval-Augmented Generation (2025.coling-main)
Copied to clipboard
| Challenge: | Retrieval-augmented generation systems often use a fixed strategy to extract information from multiple sources. |
| Approach: | They propose a method that dynamically determines optimal granularity of a knowledge source based on input queries using a router. |
| Outcome: | The proposed method predicts optimal granularity levels and significantly improves performance in downstream tasks. |
