Consensus Monte Carlo for Random Subsets using Shared Anchors
Yang Ni, Yuan Ji, Peter Mueller
We present a consensus Monte Carlo algorithm that scales existing Bayesian nonparametric models for clustering and feature allocation to big data. The algorithm is valid for any pr…
Bayesian Double Feature Allocation for Phenotyping with Electronic Health Records
Yang Ni, Peter Mueller, Yuan Ji
We propose a categorical matrix factorization method to infer latent diseases from electronic health records (EHR) data in an unsupervised manner. A latent disease is defined as an…
Scalable Bayesian Nonparametric Clustering and Classification
Yang Ni, Peter Müller, Maurice Diesendruck +3
We develop a scalable multi-step Monte Carlo algorithm for inference under a large class of nonparametric Bayesian models for clustering and classification. Each step is "embarrass…
A Bayesian Mixture Model for Clustering on the Stiefel Manifold
Subhajit Sengupta, Subhadip Pal, Riten Mitra +3
Analysis of a Bayesian mixture model for the Matrix Langevin distribution on the Stiefel manifold is presented. The model exploits a particular parametrization of the Matrix Langev…
