I have a question regarding the topic extraction with elbow method (LDA) workflow. If my assumption is correct, this workflow automatically determines the optimal number of clusters. However, I tried different datasets and in each set, I got 7 number of topics.
I attached the scatter plot I got which is just straight and looks like something is wrong with it. I also attached the screenshot of the topic extractor node where it mentioned that number of topics is 7. What I want to do is I just want the workflow to determine the number of appropriate topics.
I would be glad if you can help me with that.
