Transfer Learning with Random Coefficient Ridge Regression
Hongzhe Zhang, Hongzhe Li
Ridge regression with random coefficients provides an important alternative to fixed coefficients regression in high dimensional setting when the effects are expected to be small b…
Transfer Learning for Contextual Multi-armed Bandits
Changxiao Cai, T. Tony Cai, Hongzhe Li
Motivated by a range of applications, we study in this paper the problem of transfer learning for nonparametric contextual multi-armed bandits under the covariate shift model, wher…
Optimal Estimation of Bacterial Growth Rates Based on Permuted Monotone Matrix
Rong Ma, T. Tony Cai, Hongzhe Li
Motivated by the problem of estimating the bacterial growth rates for genome assemblies from shotgun metagenomic data, we consider the permuted monotone matrix model , wher…
Two-sample Test of Community Memberships of Weighted Stochastic Block Models
Yezheng Li, Hongzhe Li
Suppose two networks are observed for the same set of nodes, where each network is assumed to be generated from a weighted stochastic block model. This paper considers the problem…
Learning local directed acyclic graphs based on multivariate time series data
Wanlu Deng, Zhi Geng, Hongzhe Li
Multivariate time series (MTS) data such as time course gene expression data in genomics are often collected to study the dynamic nature of the systems. These data provide importan…
The sparse Laplacian shrinkage estimator for high-dimensional regression
Jian Huang, Shuangge Ma, Hongzhe Li +1
We propose a new penalized method for variable selection and estimation that explicitly incorporates the correlation patterns among predictors. This method is based on a combinatio…
