Researchers have developed a new method called Advantage-Based On-Policy Distillation (AOPD) to improve the effectiveness of online policy distillation in machine learning. Unlike standard methods that assume teacher guidance is always beneficial, AOPD weights teacher actions based on their counterfactual advantage for the current student model. This approach reinforces beneficial teacher actions while downplaying those that do not help the student succeed. AOPD can be estimated efficiently using standard student rollouts and terminal rewards, avoiding the need for additional rollouts or reward evaluations. Experiments on math, coding, and MedQA datasets demonstrate AOPD's superiority over existing distillation and reinforcement learning baselines in both external-teacher and self-distillation scenarios.
