Know When to Stop: Segment-Level Credit Assignment for Reducing Overthinking

Chia-Hsuan Lee, Sihui Dai, Mingyang Zhou +5

Reasoning language models frequently overthink: generating extended chains of behaviors such as hedging, approach abandonment, and self contradiction that consume tokens without im…

SEAD: Competence-Aware On-Policy Distillation via Entropy-Guided Supervision

Chia-Hsuan Lee, Zelei Cheng, Yu Wang +4

On-policy distillation (OPD) has a property absent in offline distillation and RL: teacher supervision quality depends on student competence. Incoherent rollouts yield noisy gradie…
