Does Qualtrics have any kind of unsupervised learning model for clustering?

Have you tried Theme detection ? I have tried it once, for the “global other” bucket for - it *MAY* help

Thank you very much, I found out that in data analysis, the clustering model uses LCA (a type of unsupervised learning) which allows correlating up to 10 variables. However, what you mentioned is very interesting for text analysis
