In clintpgeorge/ldavem: LDA Variational EM Algorithm

Description Usage Arguments Value Examples

Computes the class term frequency matrix for a given corpus.

1	calc_class_term_frequency(class.labels, vocab, doc.class.labels, documents)

`class.labels`	A vector of true class names
`vocab`	a vector of words in the vocabulary
`doc.class.labels`	a vector of document classes
`documents`	a list documents read via `read_docs`

The class term frequency matrix

documents <- read_docs('bop.ldac');
vocab <- readLines('bop.ldac.vocab');

doc.metadata <- read.csv2('bop.csv', header = T, sep = ';');
class.labels <- levels(doc.metadata[, 'category'])
ctf <- calc_class_term_frequency(class.labels, vocab, 
                                 doc.metadata[, 'category'], 
                                 documents);
