gen_synth_corpus_multi_h: Generates a Corpus with Multiple (alpha, eta)s

In clintpgeorge/ldavem: LDA Variational EM Algorithm

Description

Generates documents using the LDA generative process based on a set of (α, η) Configurations

Usage

gen_synth_corpus_multi_h(K, V, J, collection.size, doc.size, alpha.vec, eta.vec)

Arguments

K	number of topics
V	vocabulary size
J	number of collections
collection.size	number of documents in each collection (a list of J elements)
doc.size	number of words in each document
alpha.vec	a set of values for document-level Dirichlet sampling
eta.vec	a set of values for topic Diriclet sampling

## Generates documents with given parameters

J                  <- 2
K                  <- 4
V                  <- 20
alpha.vec          <- c(.2, 2)
eta.vec            <- c(.5, 2)
doc.size           <- 80
collection.size    <- c(40, 40) # number of documents in each collection
ds.name            <- paste("synth-J", J, "-K", K, "-V", V, sep = "")

ds                 <- gen_synth_corpus_multi_h(K, V, J, collection.size, doc.size, alpha.vec, eta.vec)
