Beyond Distribution Matching: Selective Margin Preservation for Supervised Fine-Tuning

Yuxuan Wang, Guangxiang Zhao, Xinyu Tan +6

Supervised fine-tuning (SFT) changes logit margins among non-target tokens at teacher-forced prefixes. Matching a local reference distribution keeps those probabilities and also pe…
