Spatial von-Mises Fisher Regression for Directional Data
Zhou Lan, Arkaprava Roy
Spatially varying directional data are routinely observed in several modern applications such as meteorology, biology, geophysics, engineering, etc. However, only a few approaches…

Double soft-thresholded model for multi-group scalar on vector-valued image regression
Arkaprava Roy, Zhou Lan
In this paper, we develop a novel spatial variable selection method for scalar on vector-valued image regression in a multi-group setting. Here, 'vector-valued image' refers to the…

Spectral Clustering, Bayesian Spanning Forest, and Forest Process
Leo L. Duan, Arkaprava Roy
Spectral clustering views the similarity matrix as a weighted graph, and partitions the data by minimizing a graph-cut loss. Since it minimizes the across-cluster similarity, there…
