Geometric Dirichlet Means algorithm for topic inference
Mikhail Yurochkin, XuanLong Nguyen
We propose a geometric algorithm for topic learning and inference that is built on the convex geometry of topics arising from the Latent Dirichlet Allocation (LDA) model and its no…

Singularity structures and impacts on parameter estimation in finite mixtures of distributions
Nhat Ho, XuanLong Nguyen
Singularities of a statistical model are the elements of the model's parameter space which make the corresponding Fisher information matrix degenerate. These are the points for whi…

On the consistency of inversion-free parameter estimation for Gaussian random fields
Hossein Keshavarz, Clayton Scott, XuanLong Nguyen
Gaussian random fields are a powerful tool for modeling environmental processes. For high dimensional samples, classical approaches for estimating the covariance parameters require…
