| Challenge: | Existing methods for factuality evaluation of LLM generation focus on facts sampled from the LM itself and might under-represent domain specific or rare facts. |
| Approach: | They propose a method that transforms a factual corpus into a benchmark evaluating an LM's propensity to generate true facts from the corpus . |
| Outcome: | The proposed framework transforms a factual corpus of interest into a benchmark evaluating an LM's propensity to generate true facts from the corpus vs. similar but incorrect statements. |
In-Context Retrieval-Augmented Language Models (2023.tacl-1)
Copied to clipboard
| Challenge: | Existing RALM methods focus on modifying the LM architecture to facilitate incorporation of external information, complicating deployment. |
| Approach: | They propose to condition a language model on relevant documents from a grounding corpus during generation by conditioning on external knowledge sources. |
| Outcome: | The proposed method significantly improves language modeling performance and provides natural source attribution mechanism. |

| Challenge: | Existing efforts to address context window limitation for off-the-shelf LLMs involve training specialized architectures. |
| Approach: | They propose a method that carves a long context into chunks and restricts attention to apply only within each window. |
| Outcome: | The proposed method shows significant improvements on in-context learning tasks with diverse input and output spaces. |
