A lower perplexity score indicates better generalization performance. In essense, since perplexity is equivalent to the inverse of the geometric mean, a lower perplexity implies data is more likely. As such, as the number of topics increase, the perplexity of the model should decrease.
for instance, What is NLP why it is required to study?
NLP is important because it helps resolve ambiguity in language and adds useful numeric structure to the data for many downstream applications, such as speech recognition or text analytics.
significantly, 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 perplexity LDA? Perplexity is a statistical measure of how well a probability model predicts a sample. As applied to LDA, for a given value of , you estimate the LDA model. Then given the theoretical word distributions represented by the topics, compare that to the actual topic mixtures, or distribution of words in your documents.

How do I know how many topics in LDA?
Method 1: Try out different values of k, select the one that has the largest likelihood. Method 3: If the HDP-LDA is infeasible on your corpus (because of corpus size), then take a uniform sample of your corpus and run HDP-LDA on that, take the value of k as given by HDP-LDA.
