From Noise to Diversity: Random Embedding Injection in LLM Reasoning

Heejun Kim, Seungpil Lee, Jewon Yeom +5

Recent soft prompt research has tried to improve reasoning by inserting trained vectors into LLM inputs, yet whether the gain comes from the learned content or from the act of inje…

System 2 Reasoning for Human-AI Alignment: Generality and Adaptivity via ARC-AGI

Sejin Kim, Sundong Kim

Despite their broad applicability, transformer-based models still fall short in System~2 reasoning, lacking the generality and adaptivity needed for human--AI alignment. We examine…
