Add graph(s) to Text Explorer to help user decide on optimal number of topics to select. Some possible methods are: Randomized SVD (RSVD), Parallel Analysis (PA), Bi-Cross Validation, Perplexity scores (see attachment). A scree type plot vs number of topics would be helpful where an inflection point would signify the chosen number of topics.
