Optimal Estimation and Completion of Matrices with Biclustering Structures
Chao Gao, Yu Lu, Zongming Ma +1
Biclustering structures in data matrices were first formalized in a seminal paper by John Hartigan (1972) where one seeks to cluster cases and variables simultaneously. Such struct…
A General Decision Theory for Huber's -Contamination Model
Mengjie Chen, Chao Gao, Zhao Ren
Today's data pose unprecedented challenges to statisticians. It may be incomplete, corrupted or exposed to some unknown source of contamination. We need new methods and theories to…
A General Framework for Bayes Structured Linear Models
Chao Gao, Aad W. van der Vaart, Harrison H. Zhou
High dimensional statistics deals with the challenge of extracting structured information from complex model settings. Compared with the growing number of frequentist methodologies…
Robust Covariance and Scatter Matrix Estimation under Huber's Contamination Model
Mengjie Chen, Chao Gao, Zhao Ren
Covariance matrix estimation is one of the most important problems in statistics. To accommodate the complexity of modern datasets, it is desired to have estimation procedures that…
Achieving Optimal Misclassification Proportion in Stochastic Block Model
Chao Gao, Zongming Ma, Anderson Y. Zhang +1
Community detection is a fundamental statistical problem in network data analysis. Many algorithms have been proposed to tackle this problem. Most of these algorithms are not guara…
