Compressed spectral screening for large-scale differential correlation analysis with application in selecting Glioblastoma gene modules
Tianxi Li, Xiwei Tang, Ajay Chatrath
Differential co-expression analysis has been widely applied by scientists in understanding the biological mechanisms of diseases. However, the unknown differential patterns are oft…
Multivariate Temporal Point Process Regression
Xiwei Tang, Lexin Li
Point process modeling is gaining increasing attention, as point process type data are emerging in numerous scientific applications. In this article, motivated by a neuronal spike…
Individualized Multilayer Tensor Learning with An Application in Imaging Analysis
Xiwei Tang, Xuan Bi, Annie Qu
This work is motivated by multimodality breast cancer imaging data, which is quite challenging in that the signals of discrete tumor-associated microvesicles (TMVs) are randomly di…
Individualized Multi-directional Variable Selection
Xiwei Tang, Fei Xue, Annie Qu
In this paper we propose a heterogeneous modeling framework which achieves individual-wise feature selection and individualized covariates' effects subgrouping simultaneously. In c…
