I conducted a topic modeling (LDA) using the R package topicmodels and successfully got a result. However, I am still not sure how I can set a key parameter, Beta (or eta), of LDA in this topicmodels package.
I know we can set the Alpha parameter by writing control=list(alpha = 0.5) in the LDA command. However, I do not know how to specify the Beta (eta) parameter in the LDA command. Does anyone know 1) how to set the Beta parameter in topicmodels R package and 2) what is the default value of Beta when we use the topicmodels package? Thank you very much for your help!!
