AEGCN: An Autoencoder-Constrained Graph Convolutional Network

Mingyuan Ma, Sen Na, Hongyu Wang

We propose a novel neural network architecture, called autoencoder-constrained graph convolutional network, to solve node classification task on graph domains. As suggested by its…

Semiparametric Nonlinear Bipartite Graph Representation Learning with Provable Guarantees

Sen Na, Yuwei Luo, Zhuoran Yang +2

Graph representation learning is a ubiquitous task in machine learning where the goal is to embed each vertex into a low-dimensional vector space. We consider the bipartite graph a…

Estimating Differential Latent Variable Graphical Models with Applications to Brain Connectivity

Sen Na, Mladen Kolar, Oluwasanmi Koyejo

Differential graphical models are designed to represent the difference between the conditional dependence structures of two groups, thus are of particular interest for scientific i…

High-dimensional Index Volatility Models via Stein's Identity

Sen Na, Mladen Kolar

We study the estimation of the parametric components of single and multiple index volatility models. Using the first- and second-order Stein's identities, we develop methods that a…

High-dimensional Varying Index Coefficient Models via Stein's Identity

Sen Na, Zhuoran Yang, Zhaoran Wang +1

We study the parameter estimation problem for a varying index coefficient model in high dimensions. Unlike the most existing works that iteratively estimate the parameters and link…
