Stochastic Variational Inference for Latent Dirichlet Allocation

Code structure from the OnlineVB code provided by Matthew D. Hoffman (mdhoffma@cs.princeton.edu) and the algorithm is as described in Hoffman's paper below

Based on the following papers:

• Latent Dirichlet Allocation by David M. Blei, Andrew Y. Ng and Michael I. Jordan
• Stochastic Variational Inference by Matthew D. Hoffman, David M. Blei, Chong Wang and John Paisley

###Also aiming to implement SVI for HDP as described in the second paper above, work in progress

###How to Use See 'Help' using python stochastic_lda.py -h

You will need:

• A file [dictionary.csv] containing your vocabular
• A file [doclist.txt] containing the list of documents in the directory that you want to sample from
• At the moment your documents can be just a normal txt file, no pre-processing required

For classwork, work in progress...

• Basic initial implementation
• Debug for common corpus
• Support Command-Line Usage for user-defined test mode and normal mode
• Run on own data
• Implement HDP
