A Unified Mechanistic Analysis of Knowledge- and Safety-Based Refusals

Yuri Son, Seunghee Kim, Hyuhng Joon Kim +1

Large language models (LLMs) are increasingly trained to decline queries that fall outside their knowledge (knowledge-based refusal, KR) or violate safety policies (safety-based re…

Query Lens: Interpreting Sparse Key-Value Features with Indirect Effects

Hwiyeong Lee, Ingyu Bang, Uiji Hwang +2

While sparse autoencoders provide features more interpretable than individual neurons, reliably characterizing them remains challenging. We propose Query Lens, which extends Logit…

UniKnow: A Unified Framework for Reliable Language Model Behavior across Parametric and External Knowledge

Youna Kim, Hyuhng Joon Kim, Minjoon Choi +4

Language models often benefit from external knowledge beyond parametric knowledge. While this combination enhances performance, achieving reliable knowledge utilization remains cha…

When to Speak, When to Abstain: Contrastive Decoding with Abstention

Hyuhng Joon Kim, Youna Kim, Sang-goo Lee +1

Large Language Models (LLMs) demonstrate exceptional performance across diverse tasks by leveraging pre-trained (i.e., parametric) and external (i.e., contextual) knowledge. While…

Adaptive Contrastive Decoding in Retrieval-Augmented Generation for Handling Noisy Contexts

Youna Kim, Hyuhng Joon Kim, Cheonbok Park +6

When using large language models (LLMs) in knowledge-intensive tasks, such as open-domain question answering, external context can bridge the gap between external knowledge and the…

Investigating the Influence of Prompt-Specific Shortcuts in AI Generated Text Detection

Choonghyun Park, Hyuhng Joon Kim, Junyeob Kim +6

AI Generated Text (AIGT) detectors are developed with texts from humans and LLMs of common tasks. Despite the diversity of plausible prompt choices, these datasets are generally co…
