Co-citation and Co-authorship Networks of Statisticians
Pengsheng Ji, Jiashun Jin, Zheng Tracy Ke +1
We collected and cleaned a large data set on publications in statistics. The data set consists of the coauthor relationships and citation relationships of 83, 331 papers published…
Power Enhancement and Phase Transitions for Global Testing of the Mixed Membership Stochastic Block Model
Louis Cammarata, Zheng Tracy Ke
The mixed-membership stochastic block model (MMSBM) is a common model for social networks. Given an -node symmetric network generated from a -community MMSBM, we would like t…
The SCORE normalization, especially for highly heterogeneous network and text data
Zheng Tracy Ke, Jiashun Jin
SCORE was introduced as a spectral approach to network community detection. Since many networks have severe degree heterogeneity, the ordinary spectral clustering (OSC) approach to…
Measurement error models: from nonparametric methods to deep neural networks
Zhirui Hu, Zheng Tracy Ke, Jun S Liu
The success of deep learning has inspired recent interests in applying neural networks in statistical inference. In this paper, we investigate the use of deep neural networks for n…
Estimation of the number of spiked eigenvalues in a covariance matrix by bulk eigenvalue matching analysis
Zheng Tracy Ke, Yucong Ma, Xihong Lin
The spiked covariance model has gained increasing popularity in high-dimensional data analysis. A fundamental problem is determination of the number of spiked eigenvalues, . For…
Community Detection for Hypergraph Networks via Regularized Tensor Power Iteration
Zheng Tracy Ke, Feng Shi, Dong Xia
To date, social network analysis has been largely focused on pairwise interactions. The study of higher-order interactions, via a hypergraph network, brings in new insights. We stu…
