LDA

Page history last edited by mike@mbowles.com 12 years, 5 months ago

Here are some links for LDA.  I'll be using slides created by Professor David Blei.  mlss09uk_blei_tm.pdf   His lecture using these slides is video-taped and is excellent.  Here's a link http://videolectures.net/mlss09uk_blei_tm/

 

Here are several other sources that flesh out various aspects of topic modeling

We'll also talk about Dirichlet distributions.  The wikipedia page for Dirichlet distribution is very helpful for getting a feel on these distributions.  http://en.wikipedia.org/wiki/Dirichlet_distribution .  Here's a paper that covers different aspects of the Dirichlet.  minka-dirichletEst.pdf

 

Here are links to some of the code that I ran in class.
