Fast moment estimation for generalized latent Dirichlet models

no code implementations17 Mar 2016 Shiwen Zhao, Barbara E. Engelhardt, Sayan Mukherjee, David B. Dunson

We illustrate the utility of our approach on simulated data, comparing results from MELD to alternative methods, and we show the promise of our approach through the application of MELD to several data sets.

Bayesian group latent factor analysis with structured sparsity

1 code implementation11 Nov 2014 Shiwen Zhao, Chuan Gao, Sayan Mukherjee, Barbara E. Engelhardt

Latent factor models are the canonical statistical tool for exploratory analyses of low-dimensional linear structure for an observation matrix with p features across n samples.

Differential gene co-expression networks via Bayesian biclustering models

no code implementations7 Nov 2014 Chuan Gao, Shiwen Zhao, Ian C. McDowell, Christopher D. Brown, Barbara E. Engelhardt

Further, we develop a method to recover gene co-expression networks from the estimated sparse biclustering matrices.
