Correct collaborative topic model It was not a correlated topic model.....
implement log likelihood of author topic model
Include example of HMM-LDA #4. The model seems to work in terms of log-likelihood, but the qualitative analysis does not show plausible results. Need more work on hyper-params or n-th order HMM.
Fix error in sampling_from_dict
Try to use the same notation across the different models.
Add an example of relational topic model. #4
Add example of author-topic model with cora dataset #4
