Readings
- LDA is not covered in Mitchell. There's a nice overview paper on LDA by David Blei.
Summary
You should know:
- d-separation, or more generally, how to determine if two variables are conditionally independent in a directed model, and what that means.
- what "explaining away" refers to.
- 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, and LDA.
