Given that I have uploaded a Latent Dirichlet Allocation implementation to my code store that uses Gibbs sampling it seemed remiss to omit an implementation that used the mean field variational method (Note that this is not the same variational method used by the original LDA paper. Its not exactly the same graphical model either - in both cases I would consider these to be (minor) improvements.). I just fixed this - it can be obtained from the usual place, in the Google code repository linked from the menu, under the directory lda_var. I also moved the gibbs sampling version to the directory lda_gibbs

Also, two updates in one month - there must be something wrong with me!
