| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary This paper presents new methods for ensuring the validity of large language models (LLMs) by providing guarantees on their output. Existing approaches in this area have two major limitations: they don’t provide conditionally valid guarantees, and they can remove valuable claims due to imperfect scoring functions. To address these challenges, the authors propose two new conformal methods. The first method generalizes a previous procedure to issue weaker guarantees when needed to preserve the utility of the output. The second method improves the quality of the scoring function through an algorithm that differentiates through the conditional conformal procedure. The authors demonstrate the effectiveness of their approach on biography and medical question-answering datasets. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary This paper makes it possible for large language models to give accurate answers with a guarantee. Right now, these models don’t always tell us if they’re sure about what they’re saying. The researchers came up with two new ways to make the model’s output more trustworthy. First, they found a way to adjust the guarantees depending on how important the answer is. Second, they improved the scoring function that helps decide whether an answer is accurate or not. They tested their methods on questions about biographies and medical topics. |
