A Domain-adaptive Physics-informed Neural Network for Inverse Problems of Maxwell's Equations in Heterogeneous Media
Shiyuan Piao, Hong Gu, Aina Wang +1
Maxwell's equations are a collection of coupled partial differential equations (PDEs) that, together with the Lorentz force law, constitute the basis of classical electromagnetism…
Evaluating robustness of support vector machines with the Lagrangian dual approach
Yuting Liu, Hong Gu, Pan Qin
Adversarial examples bring a considerable security threat to support vector machines (SVMs), especially those used in safety-critical applications. Thus, robustness verification is…
A Novel Semisupervised Contrastive Regression Framework for Forest Inventory Mapping with Multisensor Satellite Data
Shaojia Ge, Hong Gu, Weimin Su +2
Accurate mapping of forests is critical for forest management and carbon stocks monitoring. Deep learning is becoming more popular in Earth Observation (EO), however, the availabil…
Rank Selection for Non-negative Matrix Factorization
Yun Cai, Hong Gu, Toby Kenney
Non-Negative Matrix Factorization (NMF) is a widely used dimension reduction method that factorizes a non-negative data matrix into two lower dimensional non-negative matrices: One…
Deconvolution density estimation with penalised MLE
Yun Cai, Hong Gu, Toby Kenney
Deconvolution is the important problem of estimating the distribution of a quantity of interest from a sample with additive measurement error. Nearly all methods in the literature…
Pressure effect on the topologically nontrivial electronic state and transport of lutecium monobismuthide
H. Gu1, F. Tang, Y. -R. Ruan +9
Rare-earth monopnictides are predicted to be nontrivial semimetal candidates and show pressure-induced superconductivity. Here, we grow LuBi single crystal and study the magnetizat…
Magnetic-field-induced nontrivial electronic state in the Kondo-lattice semimetal CeSb
Y. Fang, F. Tang, Y. R. Ruan +10
Synergic effect of electronic correlation and spin-orbit coupling is an emerging topic in topological materials. Central to this rapidly developing area are the prototypes of stron…
SuRF: a New Method for Sparse Variable Selection, with Application in Microbiome Data Analysis
Lihui Liu, Hong Gu, Johan Van Limbergen +1
In this paper, we present a new variable selection method for regression and classification purposes. Our method, called Subsampling Ranking Forward selection (SuRF), is based on L…
Poisson PCA: Poisson Measurement Error corrected PCA, with Application to Microbiome Data
Toby Kenney, Tianshu Huang, Hong Gu
In this paper, we study the problem of computing a Principal Component Analysis of data affected by Poisson noise. We assume samples are drawn from independent Poisson distribution…
Long time behavior of solutions of Fisher-KPP equation with advection and free boundaries
Hong Gu, Bendong Lou, Maolin Zhou
We consider Fisher-KPP equation with advection: for , where and are two free boundaries satisfying Stefan conditions. This eq…
Different Asymptotic Spreading Speeds Induced by Advection in a Diffusion Problem with Free Boundaries
Hong Gu, Zhigui Lin, Bendong Lou
In this paper, we consider a Fisher-KPP equation with an advection term and two free boundaries, which models the behavior of an invasive species in one dimension space. When sprea…
