This a lecture used in the Syllabus for Machine Learning 10-601B in Spring 2016
Slides
Readings
- Muphy 27.1-27.3
- LDA is not covered in Mitchell. There's a nice overview paper on LDA by David Blei.
- Here's the code I discussed in class and some sample data.
Summary
You should know:
- what Gibbs sampling is, and how it can be used for inference in a directed graphical model.
- what the graphical models are which are associated with supervised naive Bayes, unsupervised naive Bayes, PLSI, and LDA.
- the relationships between PLSI and matrix factorization.
- how the posterior distribution in a Bayesian model can be used for dimension reduction.
