VOYAGER: A Training Free Approach for Generating Diverse Datasets using LLMs (2026.acl-long)
Copied to clipboard
| Challenge: | Large language models (LLMs) are used to generate synthetic datasets but lack diversity . prior work has noted that such generated data lacks diversity - a problem that requires domain expertise. |
| Approach: | They propose a principled approach that optimizes a mathematical quantity that optimize the diversity of the dataset using determinantal point processes. |
| Outcome: | The proposed method improves diversity by 1.5-3 times compared to baseline approaches. |
