Casual as an Anchor: Resolving Supervision Misalignment in Formality Transfer Dataset

Hyojeong Yu, Hyukhun Koh, Minsung Kim +1

Formality transfer is commonly framed as a symmetric bidirectional task between informal and formal registers. We argue that this framing conceals a supervision design flaw in exis…

Confidence-Guided Stepwise Model Routing for Cost-Efficient Reasoning

Sangmook Lee, Dohyung Kim, Hyukhun Koh +2

Recent advances in Large Language Models (LLMs) - particularly model scaling and test-time techniques - have greatly enhanced the reasoning capabilities of language models at the e…

Program Synthesis via Test-Time Transduction

Kang-il Lee, Jahyun Koo, Seunghyun Yoon +4

We introduce transductive program synthesis, a new formulation of the program synthesis task that explicitly leverages test inputs during synthesis. While prior approaches to progr…

Public Data Assisted Differentially Private In-Context Learning

Seongho Joo, Hyukhun Koh, Kyomin Jung

In-context learning (ICL) in Large Language Models (LLMs) has shown remarkable performance across various tasks without requiring fine-tuning. However, recent studies have highligh…

Harmful Prompt Laundering: Jailbreaking LLMs with Abductive Styles and Symbolic Encoding

Seongho Joo, Hyukhun Koh, Kyomin Jung

Large Language Models (LLMs) have demonstrated remarkable capabilities across diverse tasks, but their potential misuse for harmful purposes remains a significant concern. To stren…

Conditional [MASK] Discrete Diffusion Language Model

Hyukhun Koh, Minha Jhang, Dohyung Kim +2

Although auto-regressive models excel in natural language processing, they often struggle to generate diverse text and provide limited controllability. Non-auto-regressive methods…
