See like a Robot: Robot-Centric Pointmaps for Vision-Language-Action Models

Byungkun Lee, Dongyoon Hwang, Dongjin Kim +3

The paper proposes robot-centric pointmaps, which encode 3D scene coordinates in the robot's frame as image pixels, enabling vision‑language‑action models to align visual inputs wi…

3D HAMSTER: Bridging Planning and Control in Hierarchical Vision Language Action Models through 3D Trajectory Guidance

Dongyoon Hwang, Byungkun Lee, Dongjin Kim +7

Hierarchical Vision-Language-Action (VLA) models decouple high-level planning from low-level control to improve generalization in robot manipulation. Recent work in this paradigm u…

Can Large Language Models Develop Strategic Reasoning? Post-training Insights from Learning Chess

Dongyoon Hwang, Hojoon Lee, Jaegul Choo +2

While reinforcement learning (RL) for large language models (LLMs) has shown promise in mathematical reasoning, strategic reasoning for LLMs using RL remains largely unexplored. We…

SimBa: Simplicity Bias for Scaling Up Parameters in Deep Reinforcement Learning

Hojoon Lee, Dongyoon Hwang, Donghu Kim +7

Recent advances in CV and NLP have been largely driven by scaling up the number of network parameters, despite traditional theories suggesting that larger networks are prone to ove…
