retrieve topic-word array & document-topic array from lda

[Anand Viswanathan]

Situation: I have a numpy term-document matrix example: [[0,1,0,0....],....[......0,0,0,0]]. I have plugged in the above matrix to the ldamodel method of the gensim. And it is working fine with the lad method lda = LdaModel(corpus, num_topics=10). corpus is my term-document matrix mentioned above. I needed two intermediate matrices( topic-word array & document-topic array) for research purpose. 1) per document topic probability matrix (p_d_t) 2) per topic word probability matrix (p_w_t) Question: How to get those arrays from the gensim LdaModel() function.? Kindly help me with getting those matrices.

Hello Anand,

have a look at this thread: https://groups.google.com/d/msg/gensim/CJZc7KN60JE/9Xs8C0YMgq4J (and Chris' answers there).

HTH,
