    Is DPO better than PPO? What are the important ingredients to properly train RLHF for LLM? How to train them efficiently? Yi Wu from Tsinghua University gave an excellent talk on Effective RL training for LLMs at CMU LTI before #NeurIPS2024. youtube.com/watch?v=T1SeqB… @LTIatCMU

    #ACL2024 This afternoon at 2:00 pm,@WendaXu2 and I are presenting at booth 142. We analyze the self-bias of LLM for evaluation. We found that LLMs favor their own generation when doing self-evaluation (like humans) Pride and Prejudice: LLM Amplifies Self-Bias in Self-Refinement

    How to teach an AI model to reason about concepts? We release a benchmark, E-KAR, for analogical reasoning in English and Chinese. It is extremely challenging (see example next). Few AI models could do it well. Welcome to try the task at ekar-leaderboard.github.io #ACL2022

    [ACL2023] On the second day of the poster session, I presented the work WACO on speech translation. I managed to put up the other two posters on multi-language translation Lego-MT and automatic evaluation indicator SEScore2. Indeed, people asked to hear about all three papers.
