Wray Buntine will consider various problems in document analysis (named entity recognition, natural language parsing, information retrieval), and look at various probabilistic graphical models and algorithms for addressing the problem. This will not be an extensive coverage of information extrac ...

Methods for analysis of principal components in discrete data have existed for some time under various names such as grade of membership modelling, probabilistic latent semantic indexing, genotype inference with admixture, non-negative matrix factorization, latent Dirichlet allocation, multinomial P ...

This talk will cover some of our recent work in extended topic models to serve as tools in text mining and NLP (and hopefully, later, in IR) when some semantic analysis is required. In some sense our goals are akin to the use of Latent Semantic Analysis. The basic theoretical/algorithmic tool we ha ...

In topic modelling, various alternative priors have been developed, for instance asymmetric and symmetric priors for the document-topic and topic-word matrices respectively, the hierarchical Dirichlet process prior for the document-topic matrix and the hierarchical Pitman-Yor process prior for the t ...
