Power of Knockoff: The Impact of Ranking Algorithm, Augmented Design, and Symmetric Statistic
Zheng Tracy Ke, Jun S. Liu, Yucong Ma
The knockoff filter is a recent false discovery rate (FDR) control method for high-dimensional linear models. We point out that knockoff has three key components: ranking algorithm…
Optimal Estimation of the Number of Communities
Jiashun Jin, Zheng Tracy Ke, Shengming Luo +1
In network analysis, how to estimate the number of communities is a fundamental problem. We consider a broad setting where we allow severe degree heterogeneity and a wide range…
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…
