Do reviewers appropriately update their scores based on rebuttals? In this PLOS ONE paper with Ryan Liu, Steven Jecmen, Fei Fang, and Nihar Shah, we present a randomized controlled trial that suggests that, at least under certain conditions, they do. journals.plos.org/plosone/articl…

✨ Did you know that NOT using all generated rollouts in GRPO can boost your reasoning LLM? Meet PODS! We down-sample rollouts and train on just a fraction, delivering notable gains over vanilla GRPO. (1/7)
