The two scatter plots are labelled a and b. The horizontal axis in both plots is the number of topics from 2 to 14. The vertical axis is the perplexity score. In plot a for paper topics, the points decrease steadily as the number of topics increases. In plot b for patent topics, the points also decrease as the number of topics increases. Both plots show a downward trend with no reversals.
