Factorial LDA Code

This software includes an implementation of Factorial LDA (f-LDA), introduced and described in the papers below. See the included README for open licensing information as well as usage instructions and input/output formatting guidelines.

Factorial LDA is a multi-dimensional topic model because tokens are associated with an entire vector of latent variables rather than a single topic variable. This software is closed related to my multi-faceted topic models code, which includes two-dimensional models, the topic-aspect model and cross-collection LDA. I would like to eventually put all of these together, but there are enough differences that I am keeping them separate until I can do more work on it.
