PCA in Rapidminer

Member Posts: 2 Contributor I
edited November 2018 in Help

I would like to determine themes of a corpus of tweets using PCA. I created the process using the ff: read excel,nominal to numeric, PCA and connected the ports. There are no errors but I am not sure on how I can identify the hidden themes using PCA with the standard deviation, proportion of variance and cumulative variance. The proportion of variance ranges from 0-.001. I set the variance threshold at .95.
