1. You can use any metric for classification problem to evaluate the model. You can enter "what is perplexity of language models" to search answer for "perplexity", such as https://stats.stackexchange.com/questions/129352/how-to-find-the-perplexity-of-a-corpus....
Sorry, I am busy these days I have read your question, I think the problem is your model has not been written completely, or something wrong when writing the model...
> Hai Joe, thankyou so much for the coding. I want to ask about common topic. What is the interpretation for that? I really appreciate your answer because right now...
You can output them in order with the following code: the topic list: `print llda_model.topics` the term(word) list: `print llda_model.terms`
How many iterations did you use? may be you can try more iterations.
Probably because you have too little data.
Both of them will be ok. If you do not know how many iterations it takes for the model to converge, you can use (2) to get a convergent model.
Happy to help!
