VideoPDE: Unified Generative PDE Solving via Video Inpainting Diffusion Models
Edward Li, Zichen Wang, Jiahe Huang +1
We present a unified framework for solving partial differential equations (PDEs) using video-inpainting diffusion transformer models. Unlike existing methods that devise specialize…
A Simple Approach to Differentiable Rendering of SDFs
Zichen Wang, Xi Deng, Ziyi Zhang +2
We present a simple algorithm for differentiable rendering of surfaces represented by Signed Distance Fields (SDF), which makes it easy to integrate rendering into gradient-based o…
DiffusionPDE: Generative PDE-Solving Under Partial Observation
Jiahe Huang, Guandao Yang, Zichen Wang +1
We introduce a general framework for solving partial differential equations (PDEs) using generative diffusion models. In particular, we focus on the scenarios where we do not have…
Accurate Differential Operators for Hybrid Neural Fields
Aditya Chetan, Guandao Yang, Zichen Wang +2
Neural fields have become widely used in various fields, from shape representation to neural rendering, and for solving partial differential equations (PDEs). With the advent of hy…
