Effective learning of asymmetric and local features in images and other data observed on multi-dimensional grids is a challenging objective critical for a wide range of image proce…
A Bayesian hierarchical model for related densities using Polya trees
Jonathan Christensen, Li Ma
Bayesian hierarchical models are used to share information between related samples and obtain more accurate estimates of sample-level parameters, common structure, and variation be…
Mixture modeling on related samples by -stick breaking and kernel perturbation
Jacopo Soriano, Li Ma
There has been great interest recently in applying nonparametric kernel mixtures in a hierarchical manner to model multiple related data samples jointly. In such settings several d…
