Scale and curvature effects in principal geodesic analysis
Drew Lazar, Lizhen Lin
There is growing interest in using the close connection between differential geometry and statistics to model smooth manifold-valued data. In particular, much work has been done re…
Robust and Parallel Bayesian Model Selection
Michael Minyi Zhang, Henry Lam, Lizhen Lin
Effective and accurate model selection is an important problem in modern data analysis. One of the major challenges is the computational burden required to handle large data sets t…
Bayesian Sparse Linear Regression with Unknown Symmetric Error
Minwoo Chae, Lizhen Lin, David B. Dunson
We study full Bayesian procedures for sparse linear regression when errors have a symmetric but otherwise unknown distribution. The unknown error distribution is endowed with a sym…
On clustering network-valued data
Soumendu Sundar Mukherjee, Purnamrita Sarkar, Lizhen Lin
Community detection, which focuses on clustering nodes or detecting communities in (mostly) a single network, is a problem of considerable practical interest and has received a gre…
