Hi all,   I am currently using SAS Enterprise Miner 13.2 to conduct some unsupervised machine learning and I noticed that the Text Topic Node failed to classify some of inputted data. May I know if there is a way for the Text Topic Node to classify all the inputted documents?   Also, I would like to ask if there is a way to let SAS Text Topic Node to determine the optimal number of clusters to classify the documents. If this is not possible, how do you guys generally specify the number of clusters. For the moment, I'm using following the number of clusters obtained by the Text Cluster node and I'm unsure if this is recommended.   Thank you guys for your help and have a nice day! ... View more
