Researchers have developed RSTG (Recovering Learning Signals via Adaptive Teacher Guidance), a novel method to improve reinforcement learning for large language models. Existing methods like GRPO struggle with sparse rewards, while naive combinations with on-policy distillation (OPD) can degrade performance. RSTG selectively applies distillation to negative prompts, weights samples by teacher confidence, and targets specific tokens for distillation. It also incorporates supervised fine-tuning (SFT) on teacher-generated trajectories to inject positive gradients. Experiments show RSTG significantly outperforms standard approaches on math and code tasks. AI
