Style Mixing and Patchwise Prototypical Matching for One-Shot Unsupervised Domain Adaptive Semantic Segmentation

1 code implementation9 Dec 2021 Xinyi Wu, Zhenyao Wu, Yuhang Lu, Lili Ju, Song Wang

In this paper, we tackle the problem of one-shot unsupervised domain adaptation (OSUDA) for semantic segmentation where the segmentors only see one unlabeled target image during training.

Level set learning with pseudo-reversible neural networks for nonlinear dimension reduction in function approximation

2 code implementations2 Dec 2021 Yuankai Teng, Zhu Wang, Lili Ju, Anthony Gruber, Guannan Zhang

Our method contains two major components: one is the pseudo-reversible neural network (PRNN) module that effectively transforms high-dimensional input variables to low-dimensional active variables, and the other is the synthesized regression module for approximating function values based on the transformed data in the low-dimensional space.

A Comparison of Neural Network Architectures for Data-Driven Reduced-Order Modeling

1 code implementation5 Oct 2021 Anthony Gruber, Max Gunzburger, Lili Ju, Zhu Wang

The popularity of deep convolutional autoencoders (CAEs) has engendered new and effective reduced-order models (ROMs) for the simulation of large-scale dynamical systems.

Learning Green's Functions of Linear Reaction-Diffusion Equations with Application to Fast Numerical Solver

1 code implementation23 May 2021 Yuankai Teng, XiaoPing Zhang, Zhu Wang, Lili Ju

Partial differential equations are often used to model various physical phenomena, such as heat diffusion, wave propagation, fluid dynamics, elasticity, electrodynamics and image processing, and many analytic approaches or traditional numerical methods have been developed and widely used for their solutions.

Nonlinear Level Set Learning for Function Approximation on Sparse Data with Applications to Parametric Differential Equations
