Subject extract p(doc|topic) from LDA
Date Sun, 06 Jun 2010 12:13:56 GMT


I'm trying to use LDA for a collaborative filtering task, where I need to
predict the rating a user (document) will give to a movie (word).
I ran LDA and constructed T topics, but I can only print the most frequent
words (movies) per topic.
Is it possible to extract p(documet|topic) or p(word|topic) from LDA's
output? (document = new user, word = movie).

Best regards,
