UQ: Assessing Language Models on Unsolved Questions

Fan Nie, Ken Ziyu Liu, Zihao Wang +11

Benchmarks shape progress in AI research. A useful benchmark should be both difficult and realistic: questions should challenge frontier models while also reflecting real-world usa…

SFT: Efficient, Scalable and Generalizable LLM Fine-tuning by Structured Sparsity

Xinyu Yang, Jixuan Leng, Geyang Guo +5

Current PEFT methods for LLMs can achieve either high quality, efficient training, or scalable serving, but not all three simultaneously. To address this limitation, we investigate…

It Takes Two: On the Seamlessness between Reward and Policy Model in RLHF

Taiming Lu, Lingfeng Shen, Xinyu Yang +3

Reinforcement Learning from Human Feedback (RLHF) involves training policy models (PMs) and reward models (RMs) to align language models with human preferences. Instead of focusing…
