Description: Implements fast, scalable optimization algorithms for
        fitting topic models ("grade of membership" models) and
        non-negative matrix factorizations to count data. The methods
        exploit the special relationship between the multinomial topic
        model (also, "probabilistic latent semantic indexing") and
        Poisson non-negative matrix factorization. The package provides
        tools to compare, annotate and visualize model fits, including
        functions to efficiently create "structure plots" and identify
        key features in topics. The 'fastTopics' package is a successor
        to the 'CountClust' package. For more information, see
        <doi:10.48550/arXiv.2105.13440> and
        <doi:10.1186/s13059-023-03067-9>. Please also see the GitHub
        repository for additional vignettes not included in the package
        on CRAN.
