On-Policy Delta Distillation for Multilingual Math Reasoning

Byeongho Heo, Jaehui Hwang, Sangdoo Yun +1

On-Policy Distillation (OPD) is emerging as a promising alternative to reinforcement learning for LLM post-training, yet its effectiveness in multilingual settings remains underexp…

Mark, Don't Erase: Token Inoculation for Dual-Use Knowledge in LLMs

Seunghyun Lee, Dongyoon Han, Sangdoo Yun

Safety interventions on dual-use knowledge typically choose between destroying hazardous content (e.g., unlearning, filtering) and suppressing it at the output layer (e.g., refusal…

On-Policy Delta Distillation

Byeongho Heo, Jaehui Hwang, Sangdoo Yun +1

The paper proposes On-Policy Delta Distillation (OPD²), a new on‑policy distillation method that uses a delta signal—the difference between a teacher LLM and its pre‑tuned base mod…

On the Reliability of Cue Conflict and Beyond

Pum Jun Kim, Seung-Ah Lee, Seongho Park +2

Understanding how neural networks rely on visual cues offers a human-interpretable view of their internal decision processes. The cue-conflict benchmark has been influential in pro…

Oops, Wait: Discourse Tokens Matter in Reasoning Model

Jaehui Hwang, Byeongho Heo, Sangdoo Yun +1

Recent studies suggest that even data-efficient training with (1K) reasoning trajectories can induce non-trivial reasoning capabilities in large language models through pos…

SyMerge: From Non-Interference to Synergistic Merging via Single-Layer Adaptation

Aecheon Jung, Seunghwan Lee, Dongyoon Han +1

Model merging combines independently trained models into a single multi-task model. However, most existing approaches focus primarily on avoiding task interference. We argue that i…
