Physically Guided Visual Mass Estimation from a Single RGB Image
Sungjae Lee, Junhan Jeong, Yeonjoo Hong +1
Estimating object mass from visual input is challenging because mass depends jointly on geometric volume and material-dependent density, neither of which is directly observable fro…
Subspace-based Approximate Hessian Method for Zeroth-Order Optimization
Dongyoon Kim, Sungjae Lee, Wonjin Lee +1
Zeroth-order optimization addresses problems where gradient information is inaccessible or impractical to compute. While most existing methods rely on first-order approximations, i…
GraspCorrect: Robotic Grasp Correction via Vision-Language Model-Guided Feedback
Sungjae Lee, Yeonjoo Hong, Kwang In Kim
Despite significant advancements in robotic manipulation, achieving consistent and stable grasping remains a fundamental challenge, often limiting the successful execution of compl…
Piece of Table: A Divide-and-Conquer Approach for Selecting Subtables in Table Question Answering
Wonjin Lee, Kyumin Kim, Sungjae Lee +2
Applying language models (LMs) to tables is challenging due to the inherent structural differences between two-dimensional tables and one-dimensional text for which the LMs were or…
