When EOS Tokens Disagree: Understanding Length Inflation in On-Policy Distillation

Yuxiao Yang, Tianrun Yu, Shangzhe Li +6

We study length inflation in on-policy distillation (OPD), where student responses can become excessively long and even exhaust the generation budget. We identify \emph{termination…

AutoAdapt: An Automated Domain Adaptation Framework for LLMs

Sidharth Sinha, Anson Bastos, Xuchao Zhang +3

Large language models (LLMs) excel in open domains but struggle in specialized settings with limited data and evolving knowledge. Existing domain adaptation practices rely heavily…

Provable and Practical In-Context Policy Optimization for Self-Improvement

Tianrun Yu, Yuxiao Yang, Zhaoyang Wang +6

We study test-time scaling, where a model improves its answer through multi-round self-reflection at inference. We introduce In-Context Policy Optimization (ICPO), in which an agen…

REFA: Reference Free Alignment for multi-preference optimization

Taneesh Gupta, Rahul Madhavan, Xuchao Zhang +2

To mitigate reward hacking from response verbosity, modern preference optimization methods are increasingly adopting length normalization (e.g., SimPO, ORPO, LN-DPO). While effecti…
