Reviews: Discriminative Topic Modeling with Logistic LDA

ORIGINALITY The idea of having a discriminative version of LDA, analogous to logistic regression, is interesting. This idea is carried out quite well with the logistic LDA, its inference algorithm, and classification results using various datasets. QUALITY One concern I have is with comparisons with supervised LDA models, such as sLDA, discLDA, or LLDA. I realize these are mentioned in the beginning of the paper, and authors may have felt they are not as relevant, as they are not discriminative models, but I feel that readers would natural wonder about this, and authors should compare them, not necessarily empirically (thought that would be helpful). Another question I had was about topics being coherent.
