Patch-based Representation and Learning for Efficient Deformation Modeling
Ruochen Chen, Thuy Tran, Shaifali Parashar
In this paper, we present a patch-based representation of surfaces, PolyFit, which is obtained by fitting jet functions locally on surface patches. Such a representation can be lea…

ADPro: a Test-time Adaptive Diffusion Policy via Manifold-constrained Denoising and Task-aware Initialization for Robotic Manipulation
Zezeng Li, Rui Yang, Ruochen Chen +2
Diffusion policies have recently emerged as a powerful class of visuomotor controllers for robot manipulation, offering stable training and expressive multi-modal action modeling.…
