SG-OPD: Sign-Gated On-Policy Distillation via Sign-Consistency Gating and Phased Teacher Sampling
arXiv:2606.09304v1 Announce Type: cross Abstract: On-policy distillation (OPD) trains a student on its own trajectories with dense per-token supervision from a stronger teacher, and often outperforms off-policy distillation and standard reinforcement learning. However, we find that its effectiveness implicitly relies on two assumptions that frequently break in practice: trajectory-level alignment between the student and the teacher, and uniform token-level reliability of the teacher's preferences. We therefore propose Sign-Gated On-Policy Distillation (SG-OPD), which uses a binary verifier as
The continuous advancements in AI research, particularly in areas like reinforcement learning and model distillation, necessitate new methods to improve efficiency and reliability in agent training.
Improving on-policy distillation can significantly enhance the training of more robust and reliable AI agents, leading to broader and more effective applications of AI across various sectors.
The proposed SG-OPD addresses key limitations in existing on-policy distillation by introducing mechanisms for sign-consistency gating and phased teacher sampling, suggesting a new path for optimizing AI agent learning.
