Instruction Tuning with and without Context: Behavioral Shifts and Downstream Impact

Hyunji Lee, Seunghyun Yoon, Yunjae Won +7

Instruction tuning is a widely used approach to improve the instruction-following ability of large language models (LLMs). Instruction-tuning datasets typically include a mixture o…

Understanding and Enhancing Mamba-Transformer Hybrids for Memory Recall and Language Modeling

Hyunji Lee, Wenhao Yu, Hongming Zhang +4

Hybrid models that combine state space models (SSMs) with attention mechanisms have shown strong performance by leveraging the efficiency of SSMs and the high recall ability of att…

Generative Prompt Internalization

Haebin Shin, Lei Ji, Yeyun Gong +3

Prompts used in recent large language model based applications are often fixed and lengthy, leading to significant computational overhead. To address this challenge, we propose Gen…

Knowledge Entropy Decay during Language Model Pretraining Hinders New Knowledge Acquisition

Jiyeon Kim, Hyunji Lee, Hyowon Cho +6

In this work, we investigate how a model's tendency to broadly integrate its parametric knowledge evolves throughout pretraining, and how this behavior affects overall performance,…

Self-Explore: Enhancing Mathematical Reasoning in Language Models with Fine-grained Rewards

Hyeonbin Hwang, Doyoung Kim, Seungone Kim +2

Training on large amounts of rationales (i.e., CoT Fine-tuning) is effective at improving the reasoning capabilities of large language models (LLMs). However, acquiring human-autho…

How Well Do Large Language Models Truly Ground?

Hyunji Lee, Sejune Joo, Chaeeun Kim +4

To reduce issues like hallucinations and lack of control in Large Language Models (LLMs), a common method is to generate responses by grounding on external contexts given as input,…
