May 26, 2020 · The coherence score (u_mass) is from -14 to 14. But when I did my experiments, I got a score of -18 for u_mass and 0.67 for c_v. I wonder how is my u_mass ...
Jan 17, 2021 · You can use either umass or c_v. Best coherence for umass is typically the minimum. Best coherence for c_v is typically the maximum. Umass is faster than c_v, ...
The value of topic modeling is in its ability to discover inter- pretable, coherent themes from unstructured document sets, yet it is not unusual to find ...
Mar 18, 2024 · We can use the coherence score in topic modeling to measure how interpretable the topics are to humans. In this case, topics are represented as the top N words.
Aug 29, 2018 · Plotting a model's score for increasing topics resulted in lower numbers for more topics, which led me to assume that lower numbers are better.
coherence. This metric measures whether the words in a topic tend to co-occur together. We add up a score for each distinct pair of top ranked words. The ...
Hello guys, I did a evaluation of my models to choose the best k value for my topics. For evaluation I choosed the method Topic Coherence with umass.
Jul 12, 2012 · While the entropy for the UMass score stays stable for all models, NMF produces erratic entropy results under the UCI score as we learn more ...
