However, it has rarely been used for creative text because quality and diversity are hard to define in code. The authors propose QDAIF, an evolutionary method in which language models handle all three parts of QD search.… 2. **[Surveying the Effects of Quality, Diversity, and Complexity in Synthetic Data From Large Language Models](https://md.research.elamur.ai/free/en/papers/havrilla-2024-surveying-effects-quality-diversity-complexity/)** *(2024 · 17 citations)* Synthetic data produced by LLMs is now a common way to expand training sets. The methods that create it differ in seed data, generator models, prompts, filters and task-specific tricks, so it is hard to see which design choices actually help. This survey suggests judging generation algorithms by the properties of the… ## Co-authors here 12 of 14 co-authors with a page, the most papers together first. - [Andrew Dai](https://md.research.elamur.ai/free/en/authors/andrew-dai/) ×2 - [Alex Havrilla](https://md.research.elamur.ai/free/en/authors/alex-havrilla/) - [Alon Albalak](https://md.research.elamur.ai/free/en/authors/alon-albalak/) - [Duy Phung](https://md.research.elamur.ai/free/en/authors/duy-phung/) - [Hannah Teufel](https://md.research.elamur.ai/free/en/authors/hannah-teufel/) - [Herbie Bradley](https://md.research.elamur.ai/free/en/authors/herbie-bradley/) - [Jeff Clune](https://md.research.elamur.ai/free/en/authors/jeff-clune/) - [Jenny Zhang](https://md.research.elamur.ai/free/en/authors/jenny-zhang/) - [Joel Lehman](https://md.research.elamur.ai/free/en/authors/joel-lehman/) - [Kanishk Gandhi](https://md.research.elamur.ai/free/en/authors/kanishk-gandhi/) - [Kenneth Owen Stanley](https://md.research.elamur.ai/free/en/authors/kenneth-owen-stanley/) - [Laura O'Mahony](https://md.research.elamur.ai/free/en/authors/laura-o-mahony/) ## Cited by Papers of our library cite their works 25 times (of the 149,439 papers whose bibliographies we read); [9 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/koen-oostermeijer/cited-by/).
