Topic Coherence/Topic Diversity
Finally, it is time to look at the graphs of the model with the highest topic coherence. Technically, this would be 150 topics with an NPMI coherence of 0.03736, however this is with a lower topic diversity 0.8593. Comparatively, 90 topics has similar NPMI coherence of 0.03663 but a higher topic diversity of 0.8978. Therefore, 90 topics is the highest quality model with regards to both metrics.
