Subsequently, How do you find perplexity?
As you said in your question, the probability of a sentence appear in a corpus, in a unigram model, is given by p(s)=∏ni=1p(wi), where p(wi) is the probability of the word wi occurs. We are done. And this is the perplexity of the corpus to the number of words.
How do you interpret perplexity?
We can interpret perplexity as the weighted branching factor. If we have a perplexity of 100, it means that whenever the model is trying to guess the next word it is as confused as if it had to pick between 100 words.
What does negative perplexity mean? Having negative perplexity apparently is due to infinitesimal probabilities being converted to the log scale automatically by Gensim, but even though a lower perplexity is desired, the lower bound value denotes deterioration (according to this), so the lower bound value of perplexity is deteriorating with a larger …

What is CV coherence? CV is based on a sliding window, a one-set segmentation of the top words and an indirect confirmation measure that uses normalized pointwise mutual information (NPMI) and the cosinus similarity. This coherence measure retrieves cooccurrence counts for the given words using a sliding window and the window size 110.
What is the difference between aver and avow?
