Entropy Interventions Do Not Transfer: Why RLVR Entropy Control Misfires in On-Policy Distillation

Reinforcement learning with verifiable rewards (RLVR) controls policy entropy by reweighting tokens against an external scalar advantage. On-policy distillation (OPD) faces the same surface problem, a student that can sharpen too fast, but it replaces that advantage with a per-token teacher target. That shared symptom...

Learning from Interaction Experience via Localized Context Distillation

Learning from interaction experience is essential for enabling large language models to continually improve during deployment. Context distillation offers a promising path: privileged information extracted from experience is provided to a teacher, whose behavior is then distilled into a student model that has no access...

Matching Supervision to the Student's Learning Capacity: A Unified Framework for On-Policy Self-Distillation

Unified On-Policy Self-Distillation (USD), a lightweight online algorithm to solve the Lagrangian, reveals that a single dual variable governs both decisions: at one price for learning difficulty, it simultaneously sets the token-selection threshold and the direction of privileged-information adjustment, keeping superv...
