The Generalized Method of Moments for Mixture and Mixed Models

Huang, Zhiyue (University of Waterloo, 2015-09-28)

Mixture models can be found in a wide variety of statistical applications. However, undertaking statistical inference in mixture models, especially non-parametric mixture models, can be challenging. A general, or nonparametric, ...
Local Mixture Model in Hilbert Space

Zhiyue, Huang (University of Waterloo, 2010-01-26)

In this thesis, we study local mixture models with a Hilbert space structure. First, we consider the fibre bundle structure of local mixture models in a Hilbert space. Next, the spectral decomposition is introduced in order ...
A Study of Using Chinese Restaurant Process Mixture Models in Information Retrieval

Lin, Wu (University of Waterloo, 2015-01-16)

Retrieval systems help users to isolate relevant information from massive data collections. Usually, a user obtains useful information by submitting a query to such a system. One critical issue is that a query could have ...
