Although task-level RLVR improves the teacher's independent problem-solving ability, it does not resolve the distribution mismatch between teacher and student.

UnverifiedIn PIVOT, supervision acts only on the inserted teacher correction segments, while the original student tokens are still driven by the RLVR reward, and the two types of losses are optimized jointly.72% similarUnverifiedCompared to reinforcement learning from human feedback (RLHF), RLVR does not rely on human annotators, has extremely low marginal cost, and can be run at a scale far exceeding that of RLHF.71% similarUnverifiedThe optimization landscape of RLVR is fundamentally different from supervised learning: the reward signal is sparse and discrete, gradient estimates come from sampled responses, and the variance is significantly higher than in traditional training settings.70% similarUnverifiedUnlike supervised learning, reinforcement learning does not require labeled data but instead learns optimal behavior through trial and error.70% similarUnverifiedRLVR (reinforcement learning with verifiable rewards) performs excellently on in-distribution tasks, but its performance drops significantly (policy collapse) when transferred out of distribution (OOD).68% similar
