Scheduling Thoughts: Learning the Order of Thought in Diffusion Language Models

Jiawei Xu, Minghui Liu, Aakriti Agrawal +2

Masked diffusion language models decode by iteratively unmasking tokens, where the unmasking order defines an "order of thought" that strongly influences generation quality yet is…

When Human Preferences Flip: An Instance-Dependent Robust Loss for RLHF

Yifan Xu, Xichen Ye, Yifan Chen +1

Quality of datasets plays an important role in large language model (LLM) alignment. In collecting human feedback, however, preference flipping is ubiquitous and causes corruption…
