Finite Mixtures of Multivariate Poisson-Log Normal Factor Analyzers for Clustering Count Data

1 code implementation13 Nov 2023 Andrea Payne, Anjali Silva, Steven J. Rothstein, Paul D. McNicholas, Sanjeena Subedi

A mixture of multivariate Poisson-log normal factor analyzers is introduced by imposing constraints on the covariance matrix, which resulted in flexible models for clustering purposes.

Finite mixtures of matrix-variate Poisson-log normal distributions for three-way count data

1 code implementation22 Jul 2018 Anjali Silva, Steven J. Rothstein, Paul D. McNicholas, Sanjeena Subedi

Matrix variate distributions offer a natural way to model three-way data and mixtures of matrix variate distributions can be used to cluster three-way data.

A Multivariate Poisson-Log Normal Mixture Model for Clustering Transcriptome Sequencing Data

2 code implementations30 Nov 2017 Anjali Silva, Steven J. Rothstein, Paul D. McNicholas, Sanjeena Subedi

The aim of applying mixture model-based clustering in this context is to discover groups of co-expressed genes, which can shed light on biological functions and pathways of gene products.
