Functional Bayesian Networks for Discovering Causality from Multivariate Functional Data

Fangting Zhou, Kejun He, Kunbo Wang +2

Multivariate functional data arise in a wide range of applications. One fundamental task is to understand the causal relationships among these functional objects of interest, which…

A Bayesian Nonparametric Approach for Inferring Drug Combination Effects on Mental Health in People with HIV

Wei Jin, Yang Ni, Leah H. Rubin +2

Although combination antiretroviral therapy (ART) is highly effective in suppressing viral load for people with HIV (PWH), many ART agents may exacerbate central nervous system (CN…

Efficient Estimation for Random Dot Product Graphs via a One-step Procedure

Fangzheng Xie, Yanxun Xu

We propose a one-step procedure to estimate the latent positions in random dot product graphs efficiently. Unlike the classical spectral-based methods such as the adjacency and Lap…

Optimal Bayesian Estimation for Random Dot Product Graphs

Fangzheng Xie, Yanxun Xu

We propose a Bayesian approach, called the posterior spectral embedding, for estimating the latent positions in random dot product graphs, and prove its optimality. Unlike the clas…

BAREB: A Bayesian repulsive biclustering model for periodontal data

Yuliang Li, Dipankar Bandyopadhyay, Fangzheng Xie +1

Preventing periodontal diseases (PD) and maintaining the structure and function of teeth are important goals for personal oral care. To understand the heterogeneity in patients wit…

Bayesian Estimation of Sparse Spiked Covariance Matrices in High Dimensions

Fangzheng Xie, Yanxun Xu, Carey E. Priebe +1

We propose a Bayesian methodology for estimating spiked covariance matrices with jointly sparse structure in high dimensions. The spiked covariance matrix is reparametrized in term…
