JASPER: Joint Bayesian Analysis of Spatial Expression via Regression
Pritam Dey, Rajarshi Guhaniyogi, Yang Ni +1
Spatially resolved transcriptomics is a fast-developing set of technologies that enables the measurement of localized gene expression across spatial locations in a sample. Detectin…
Structure Learning for Directed Trees with Zero-Inflated Compositional Nodes
Shuangjie Zhang, Bani K. Mallick, Yang Ni
Compositional data, which are vectors of proportions constrained to the probability simplex, arise frequently in modern scientific applications, including microbiome relative abund…
Nested Atoms Model with Application to Clustering Big Population-Scale Single-Cell Data
Arhit Chakrabarti, Yang Ni, Yuchao Jiang +1
We consider the problem of clustering nested or hierarchical data, where observations are grouped and there are both group-level and observation-level variables. In our motivating…
Global-Local Dirichlet Processes for Identifying Pan-Cancer Subpopulations Using Both Shared and Cancer-Specific Data
Arhit Chakrabarti, Yang Ni, Debdeep Pati +1
We consider the problem of clustering grouped data for which the observations may include group-specific variables in addition to the variables that are shared across groups. This…
