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…

DIAR: Diffusion-model-guided Implicit Q-learning with Adaptive Revaluation

Jaehyun Park, Yunho Kim, Sejin Kim +2

We propose a novel offline reinforcement learning (offline RL) approach, introducing the Diffusion-model-guided Implicit Q-learning with Adaptive Revaluation (DIAR) framework. We a…
