Bayesian Semiparametric Longitudinal Inverse-Probit Mixed Models for Category Learning

Minerva Mukhopadhyay, Jacie R. McHaney, Bharath Chandrasekaran +1

Understanding how the adult human brain learns novel categories is an important problem in neuroscience. Drift-diffusion models are popular in such contexts for their ability to mi…

Bayesian Semiparametric Hidden Markov Tensor Partition Models for Longitudinal Data with Local Variable Selection

Giorgio Paulon, Peter Müller, Abhra Sarkar

We present a flexible Bayesian semiparametric mixed model for longitudinal data analysis in the presence of potentially high-dimensional categorical covariates. Building on a novel…

Bayesian Scalable Precision Factor Analysis for Massive Sparse Gaussian Graphical Models

Noirrit Kiran Chandra, Peter Mueller, Abhra Sarkar

We propose a novel approach to estimating the precision matrix of multivariate Gaussian data that relies on decomposing them into a low-rank and a diagonal component. Such decompos…

Bayesian Semiparametric Markov Renewal Mixed Models for Vocalization Syntax

Yutong Wu, Erich D. Jarvis, Abhra Sarkar

Studying the neurological, genetic and evolutionary basis of human vocal communication mechanisms is an important field of neuroscience. In the absence of high quality data on huma…

Bayesian Semiparametric Multivariate Density Deconvolution via Stochastic Rotation of Replicates

Arkaprava Roy, Abhra Sarkar

We consider the problem of multivariate density deconvolution where the distribution of a random vector needs to be estimated from replicates contaminated with conditionally hetero…
