I'm using LDA package in R for topic modeling and get confused on the parameter setting in the function slda.em.
slda.em(documents, K, vocab, num.e.iterations, num.m.iterations, alpha,
eta, annotations, params, variance, logistic = FALSE, lambda = 10,
regularise = FALSE, method = "sLDA", trace = 0L, MaxNWts=3000)
From my understanding, sLDA model can fit and predict response values for new documents. So I am wondering if the annotation represents response/label in slda? If not what does annotation mean? And which parameter should I regard as response? Thank you!
