Papers with fine-tuned LLMs
Okapi: Instruction-tuned Large Language Models in Multiple Languages with Reinforcement Learning from Human Feedback (2023.emnlp-demo)
Copied to clipboard
| Challenge: | Existing instruction-tuned open-source LLMs have only been instruction- tuned for English and a few popular languages, thus hindering their accessibility to many other languages in the world. |
| Approach: | They propose a framework that uses supervised fine-tuning and reinforcement learning from human feedback to improve the accessibility of large language models. |
| Outcome: | The proposed framework enables the evaluation of generative LLMs in multiple languages. |

| Challenge: | Large Language Models (LLMs) on sensitive datasets carry a substantial risk of unintended memorization and leakage of Personally Identifiable Information (PII) prior studies have analyzed memorizing dynamics in LLMs during pre-training and fine-tuning. |
| Approach: | They investigate the vulnerability of PII that appears only in model inputs, not in training targets. |
| Outcome: | The proposed methods show that post-training methods provide more consistent privacy-utility trade-offs . |
