Conformity-Based Bayesian Projective Prediction
Arkaprava Roy, Malay Ghosh
We propose a general robust prediction framework, termed conformity-based projective prediction (CPP), that integrates Bayesian predictive modeling with ideas from conformity-based…

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…
