An Introduction to Topic Modeling

Daniel Peterson of the Center for Computational Language and Education Research (CLEAR) at CU Boulder will be presenting an overview of topic modeling.

 

Abstract:

Topic modeling is currently receiving a great deal of interest, because it successfully condenses a corpus full of information into small, often semantically-interpretable chunks of terms (topics). These topics are actually full unigram language models - each one represents the sorts of terms that get used in a particular style of document. Topic modeling works by asserting a probabilistic generative model that created the documents, and then using Bayesian inference to infer the parameters underlying this model, given the output (the corpus of interest). In this talk I will give an overview of the generative model and the sampling process, and try to convey an understanding for why and how topic modeling works.

 

Bio:

Daniel Peterson grew up in Wyoming. He has a BA in Mathematics and a MS in Electrical Engineering, both from the University of Wyoming. Currently he is in the 2nd year of a PhD program in Natural Language Processing from the University of Colorado. His current interests and research are in unsupervised clustering algorithms, including topic modeling and Bayesian modeling in general. With a background in math an interest in a project, you can get pretty far.

    I guess I'll link to my own blog too where I talked a little bit on Topic Modeling and added the command lines I start with: http://gibrown.wordpress.com/20...­

    Will there be food and beverages?

      We don't have any food/beverages planned for this meetup, something we can talk about if anyone is interested in sponsoring in the future. Lee and I are both planning on heading out somewhere (undetermined) for dinner afterwards if anyone is interested in joining. The dinner afterwards was almost as much fun as the meetup last time.

    That's a shame. This is at the same time as the Full-Stack meetup.
