Title:  Algorithms for Mixture Models: Analysis and Experiments
 
Abstract:
 
Mixture models form one of the most fundamental classes of generative models
for clustered data, and they have numerous applications in information
retrieval, computer vision, and other fields.  However, until very recently,
there have been only a few algorithms known that can provably guarantee
reconstruction of the model with small error, given observed data.  In this
talk we present algorithms for two different learning problems which enjoy
this property.  We also present results of experiments performed on
collection of abstracts from ArXiV using one of our algorithms.
 
One interesting property shared by both our algorithms is that they are
based on the use of the L1-norm, and we show that it is a better choice than
Euclidean norm for these problems.
