Bayesian Semiparametric Hidden Markov Random Partition Fields for Factor Collapse on Graphs: A Study of Cortical Mapping of Fingertips

Blake Moya, Kevin Sitek, Arkaprava Roy +2

Understanding how the brain's cortical regions respond to stimuli like fingertip tapping is a significant challenge in neuroscience, especially with high-resolution functional magn…

An Additive MLP-GNN Framework for Characterizing Chemical and Structural Contributions to Aqueous Solubility

Sampreeti Bhattacharya, Arkaprava Roy

Aqueous solubility is a key property in early-stage drug discovery, but most predictive models merge physicochemical descriptors and molecular graph information into a single repre…

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…

Nonparametric Modeling of Diffusion MRI Signal in Q-space

Arkaprava Roy, Zhou Lan, Zhengwu Zhang

This paper describes a novel nonparametric model for modeling diffusion MRI signals in q-space. In q-space, diffusion MRI signal is measured for a sequence of magnetic strengths (b…

Conic Sparsity: Estimation of Regression Parameters in Closed Convex Polyhedral Cones

Neha Agarwala, Arkaprava Roy, Anindya Roy

Statistical problems often involve linear equality and inequality constraints on model parameters. Direct estimation of parameters restricted to general polyhedral cones, particula…

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…
