Gradients Must Earn Their Influence: Unifying SFT with Generalized Entropic Objectives

Zecheng Wang, Deyuan Liu, Chunshan Li +5

Standard negative log-likelihood (NLL) for Supervised Fine-Tuning (SFT) applies uniform token-level weighting. This rigidity creates a two-fold failure mode: (i) overemphasizing lo…

Leveraging Adversarial Training in Self-Learning for Cross-Lingual Text Classification

Xin Dong, Yaxin Zhu, Yupeng Zhang +4

In cross-lingual text classification, one seeks to exploit labeled data from one language to train a text classification model that can then be applied to a completely different la…
