> The LDA output does not include the topic-probability distribution per

> The current implementation of LDA outputs only topics and their words. Many
> applications need the p(z|d) values of a document to use this vector as a
> reduced representation of the document (dimensionality reduction of
> document). We need to introduce a new key which would keep track of the gamma
> values for each document (as obtained from the document.infer() method) and
> writes these to the output stream and finally, PrintLDATopics should output
> these values per document id. Also, outputting the probabilities of words in
> a topic would also provide a more meaningful output.
