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…

Multi-Preference Optimization: Generalizing DPO via Set-Level Contrasts

Taneesh Gupta, Rahul Madhavan, Xuchao Zhang +3

Direct Preference Optimization (DPO) has become a popular approach for aligning language models using pairwise preferences. However, in practical post-training pipelines, on-policy…
