A generalized Bayes framework for probabilistic clustering

no code implementations9 Jun 2020 Tommaso Rigon, Amy H. Herring, David B. Dunson

Several existing clustering algorithms, including k-means, can be interpreted as generalized Bayes estimators under our framework, and hence we provide a method of uncertainty quantification for these approaches.

Bayesian joint modeling of chemical structure and dose response curves

1 code implementation27 Dec 2019 Kelly R. Moran, David Dunson, Amy H. Herring

Our model also enables the prediction of chemical dose-response profiles based on chemical structure (that is, without in vivo or in vitro testing) by taking advantage of a large database of chemicals that have already been tested for toxicity in HTS programs.

Perturbed factor analysis: Improving generalizability across studies

1 code implementation7 Oct 2019 Arkaprava Roy, Isaac Lavine, Amy H. Herring, David B. Dunson

As an alternative, we propose a class of Perturbed Factor Analysis (PFA) models that assume a common factor structure across studies after perturbing the data via multiplication by a study-specific matrix.

Bayesian Hierarchical Factor Regression Models to Infer Cause of Death From Verbal Autopsy Data

1 code implementation20 Aug 2019 Kelly R. Moran, Elizabeth L. Turner, David Dunson, Amy H. Herring

In low-resource settings where vital registration of death is not routine it is often of critical interest to determine and study the cause of death (COD) for individuals and the cause-specific mortality fraction (CSMF) for populations.
