A Universal PINNs Method for Solving Partial Differential Equations with a Point Source

1 code implementation Proceedings of the Thirty-First International Joint Conference on Artificial Intelligence 2022 Xiang Huang, Hongsheng Liu, Beiji Shi, Zidong Wang, Kang Yang, Yang Li, Min Wang, Haotian Chu, Jing Zhou, Fan Yu, Bei Hua, Bin Dong, Lei Chen

In recent years, deep learning technology has been used to solve partial differential equations (PDEs), among which the physics-informed neural networks (PINNs)method emerges to be a promising method for solving both forward and inverse PDE problems.

Computing Real Numbers with Large-Population Protocols Having a Continuum of Equilibria

no code implementations14 Jun 2022 Xiang Huang, Rachel N. Huls

As a result, a number is computable by an LPP if and only if it is algebraic, namely, not a single transcendental number can be computed under this notion.

PhyIR: Physics-Based Inverse Rendering for Panoramic Indoor Images

1 code implementation CVPR 2022 Zhen Li, Lingli Wang, Xiang Huang, Cihui Pan, Jiaqi Yang

In this paper, we present PhyIR, a neural inverse rendering method with a more completed SVBRDF representation and a physics-based in-network rendering layer, which can handle complex material and incorporate physical constraints by re-rendering realistic and detailed specular reflectance.

A Distributed Synchronous SGD Algorithm with Global Top-$k$ Sparsification for Low Bandwidth Networks

1 code implementation14 Jan 2019 Shaohuai Shi, Qiang Wang, Kaiyong Zhao, Zhenheng Tang, Yuxin Wang, Xiang Huang, Xiaowen Chu

Current methods that use AllGather to accumulate the sparse gradients have a communication complexity of $O(kP)$, where $P$ is the number of workers, which is inefficient on low bandwidth networks with a large number of workers.

U-SLADS: Unsupervised Learning Approach for Dynamic Dendrite Sampling

1 code implementation6 Jul 2018 Yan Zhang, Xiang Huang, Nicola Ferrier, Emine B. Gulsoy, Charudatta Phatak

Novel data acquisition schemes have been an emerging need for scanning microscopy based imaging techniques to reduce the time in data acquisition and to minimize probing radiation in sample exposure.
