SCOPE: Signal-Calibrated On-Policy Distillation Enhancement with Dual-Path Adaptive Weighting
arXiv:2604.10688v2 Announce Type: replace-cross Abstract: On-policy reinforcement learning has become the dominant paradigm for reasoning alignment in large language models, yet its sparse, outcome-level rewards make token-level credit assignment notoriously difficult. On-Policy Distillation (OPD) alleviates this by introducing dense, token-level KL supervision from a teacher model, but typically applies this supervision uniformly across all rollouts, ignoring fundamental differences in signal quality. We propose Signal-Calibrated On-Policy Distillation Enhancement (SCOPE), a dual-path adaptiv
The rapid advancement and adoption of large language models necessitate more efficient and effective methods for alignment and credit assignment, pushing innovation in on-policy reinforcement learning.
Improved on-policy distillation techniques like SCOPE could significantly enhance the training efficiency and performance of large language models, accelerating their capabilities and deployment across various applications.
The methodology for training advanced AI models, particularly in assigning credit for success or failure at a granular level, becomes more sophisticated and efficient, potentially leading to faster development cycles and more robust AI.
