A majority of the topic models that I had been able to decode were ones found within the 100 topic range and only a few within the 50 topic range. If I had used more than around 20 words, the topics would become too broad. All iterations were around 2,000 iterations. I happen to find one of a rather interesting and almost humorous topic.
