When Not to Trust Language Models: Investigating Effectiveness of Parametric and Non-Parametric Memories (2023.acl-long)
Copied to clipboard
| Challenge: | Large language models struggle with tasks requiring rich world knowledge, implying the difficulty of encoding a wealth of world knowledge in their parameters. |
| Approach: | They propose a retrieval-augmentation method that improves performance and reduces inference costs by only retrieving non-parametric memories when necessary. |
| Outcome: | The proposed method improves performance and reduces inference costs by only retrieving non-parametric memories when necessary. |
