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. It is also covered in Murphy ch 27.3 (don't read 27.3.6) and 27.4.

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.
