Parsimonious Mixtures of Skewed Bilinear Factor Analyzers
Jacob Moore, Michael P. B. Gallaugher
The paper introduces a parsimonious family of 256 mixture models for clustering skewed matrix‑valued data using skew‑t bilinear factor analyzers, with an AECM algorithm for estimat…

Flexible Clustering with a Sparse Mixture of Generalized Hyperbolic Distributions
Alexa A. Sochaniwsky, Michael P. B. Gallaugher, Yang Tang +1
Robust clustering of high-dimensional data is an important topic because clusters in real datasets are often heavy-tailed and/or asymmetric. Traditional approaches to model-based c…
