%description
Implements an algorithm for Latent Dirichlet Allocation (LDA), Blei et at.
(2003) <https://www.jmlr.org/papers/volume3/blei03a/blei03a.pdf>, using
style conventions from the 'tidyverse', Wickham et al.
(2019)<doi:10.21105/joss.01686>, and 'tidymodels', Kuhn et
al.<https://tidymodels.github.io/model-implementation-principles/>.
Fitting is done via collapsed Gibbs sampling. Also implements several
novel features for LDA such as guided models and transfer learning based
on ongoing and, as yet, unpublished research.
