functions. mlvocab
functions accept nbuckets
argument for partial or full hashing of the corpus.Current functionality includes:
tix_seq()
, tix_mat()
and tix_df()
produce integer sequences suitable for direct consumption by various sequence models.dtm()
, tdm()
and tcm()
create document-term term-document and term-co-occurrence matrices respectively.prune_embeddings()
creates smaller embedding matrices treating missing and unknown vocabulary terms with grace.tfidf()
computes various versions of term frequency, inverse document frequency weighting of dtm
and tdm
matrices.Package is in alpha state. API changes are likely.
