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…

Nonparametric Deconvolution and Denoising using Simulation Based Inference

Ritwik Vashistha, Abhra Sarkar, Arya Farahi

Latent signals are often obscured by measurement noise, yet encode the underlying laws and dynamics of complex systems; learning both the signals and their distributions remains a…

Convolutional Maximum Mean Discrepancy for Inference in Noisy Data

Ritwik Vashistha, Jeff M. Phillips, Abhra Sarkar +1

Modern data analyses frequently encounter settings where samples of variables are contaminated by measurement error. Ignoring measurement noise can substantially degrade statistica…

Bayesian Semiparametric Multivariate Density Regression with Coordinate-Wise Predictor Selection

Giovanni Toto, Peter Müller, Abhra Sarkar

We propose a flexible Bayesian approach for estimating the joint density of a multivariate outcome of interest in the presence of categorical covariates. Leveraging a Gaussian copu…

Bayesian Mixed Multidimensional Scaling for Auditory Processing

Giovanni Rebaudo, Fernando Llanos, Bharath Chandrasekaran +1

The human brain distinguishes speech sounds by mapping acoustic signals into a latent perceptual space. This space can be estimated via multidimensional scaling (MDS), preserving t…

Bayesian Tensor Factorized Vector Autoregressive Models for Inferring Granger Causality Patterns from High-Dimensional Multi-subject Panel Neuroimaging Data

Jingjing Fan, Kevin Sitek, Bharath Chandrasekaran +1

Understanding the dynamics of functional brain connectivity patterns using noninvasive neuroimaging techniques is an important focus in human neuroscience. Vector autoregressive (V…
