Density Evolution: A Multiscale View of Density Estimation
Kisung You
Density estimation is often presented as a choice among parametric summaries, finite mixtures, and nonparametric smoothers. This review argues for a complementary view: a data set…
Scale selection for geometric medians on product manifolds
Kisung You
Geometric medians on product manifolds are sensitive to the relative scaling of factor metrics because the median objective couples the factors rather than separating them. We stud…
Profile Likelihood Inference for Anisotropic Hyperbolic Wrapped Normal Models on Hyperbolic Space
Kisung You
We study likelihood-based inference for the anisotropic hyperbolic wrapped normal distribution on standard hyperbolic space. The model has a manifold-valued location parameter and…
Learning Subspaces of Different Dimension
Brian St. Thomas, Lizhen Lin, Lek-Heng Lim +1
We introduce a Bayesian model for inferring mixtures of subspaces of different dimensions. The key challenge in such a mixture model is specification of prior distributions over su…
