Bridged Self-Distillation Unifies On-Policy Reasoning Transfer

By PulseAugur Editorial · [2 sources] ·

Researchers have introduced Bridged Self-Distillation (BSD), a novel framework designed to unify on-policy reasoning transfer from any teacher model to a smaller student model. BSD addresses mismatches in imitation difficulty and token-level probability compatibility by using privileged reasoning traces from an external teacher. A self-teacher, a copy of the student model, scores rollouts in the student's token space, guiding updates on unsuccessful rollouts with outcome verification. This unified approach applies to various teacher scenarios, including shared-tokenizer, cross-tokenizer, and closed API teachers, outperforming existing baselines. AI

IMPACT This framework offers a unified approach to model distillation, potentially improving the efficiency and effectiveness of transferring capabilities from larger to smaller AI models.

    Bridged Self-Distillation for On-Policy Learning

    On-policy distillation can transfer the reasoning capabilities of a strong teacher to a smaller student. However, distillation from a stronger teacher model faces two mismatches: its solutions may be difficult for a smaller student to imitate, and its token-level probabilities ma…
