Decoupling shrinkage and selection in Bayesian linear models: a posterior summary perspective

PR Hahn, CM Carvalho - Journal of the American Statistical …, 2015 - Taylor & Francis
Selecting a subset of variables for linear models remains an active area of research. This
article reviews many of the recent contributions to the Bayesian model selection and …

Bayesian inference for logistic models using Pólya–Gamma latent variables

NG Polson, JG Scott, J Windle - Journal of the American statistical …, 2013 - Taylor & Francis
We propose a new data-augmentation strategy for fully Bayesian inference in models with
binomial likelihoods. The approach appeals to a new class of Pólya–Gamma distributions …

A simple sampler for the horseshoe estimator

E Makalic, DF Schmidt - IEEE Signal Processing Letters, 2015 - ieeexplore.ieee.org
In this note we derive a simple Bayesian sampler for linear regression with the horseshoe
hierarchy. A new interpretation of the horseshoe model is presented, and extensions to …

[PDF][PDF] Shrink globally, act locally: Sparse Bayesian regularization and prediction

NG Polson, JG Scott - Bayesian statistics, 2010 - Citeseer
We use Lévy processes to generate joint prior distributions for a location parameter β=(β1,...,
βp) as p grows large. This approach, which generalizes normal scale-mixture priors to an …

On the half-Cauchy prior for a global scale parameter

NG Polson, JG Scott - Bayesian Analysis, 2012 - projecteuclid.org
This paper argues that the half-Cauchy distribution should replace the inverse-Gamma
distribution as a default prior for a top-level scale parameter in Bayesian hierarchical …

Prior distributions for objective Bayesian analysis

G Consonni, D Fouskakis, B Liseo, I Ntzoufras - 2018 - projecteuclid.org
We provide a review of prior distributions for objective Bayesian analysis. We start by
examining some foundational issues and then organize our exposition into priors for: i) …

Lasso meets horseshoe

A Bhadra, J Datta, NG Polson, B Willard - Statistical Science, 2019 - JSTOR
The goal of this paper is to contrast and survey the major advances in two of the most
commonly used high-dimensional techniques, namely, the Lasso and horseshoe …

Compressive hyperspectral imaging with side information

X Yuan, TH Tsai, R Zhu, P Llull… - IEEE Journal of …, 2015 - ieeexplore.ieee.org
A blind compressive sensing algorithm is proposed to reconstruct hyperspectral images from
spectrally-compressed measurements. The wavelength-dependent data are coded and then …

Proximal algorithms in statistics and machine learning

NG Polson, JG Scott, BT Willard - 2015 - projecteuclid.org
Proximal algorithms are useful for obtaining solutions to difficult optimization problems,
especially those involving nonsmooth or composite objective functions. A proximal algorithm …

Bayesian tensor regression

R Guhaniyogi, S Qamar, DB Dunson - Journal of Machine Learning …, 2017 - jmlr.org
We propose a Bayesian approach to regression with a scalar response on vector and tensor
covariates. Vectorization of the tensor prior to analysis fails to exploit the structure, often …
