| Challenge: | Parameter-efficient reinforcement learning (PE-RL) is a highly effective training regime to improve large language models’ ability to answer queries on sensitive topics with a Neutral Point of View (NPOV). |
| Approach: | They propose to use parameter-efficient reinforcement learning to train large language models to answer queries with a Neutral Point of View (NPOV) This is compared to the strongest baseline, LoRA finetuning, SFT and RLHF. |
| Outcome: | The proposed training regime improves on NPOV quality and scores higher on features identified by linguists as key to separating good answers from the best answers. |

| Challenge: | generative models have been known to have reduced performance in different global cultural contexts and languages. |
| Approach: | They construct a pipeline to collect and contribute culturally salient, multilingual data . they argue such data can assess the state of the global applicability of generative AI models . |
| Outcome: | The proposed pipeline can assess the state of the global applicability of our models and improve upon cross-cultural gaps. |
