[experimental] Compute perplexity of a model

Compute the perplexity of a trained word2vec model with data.

Usage

perplexity(x, targets, data, layer = c("words", "documents"))

Arguments

x

a trained textmodel_wordvector object.

data

a quanteda::tokens or quanteda::dfm; the probabilities of words are tested against occurrences of words in it.
