alto is an R package for aligning
topics across a collection of LDA models. It provides functions to support the
most common tasks in the analysis workflow,
run_lda_models()fits a collection of LDA models across resolution levelsalign_topics()aligns topics across a collection of LDA modelstopics()provides metrics of alignment qualityplot()shows the flow of alignment weight across resolution levelsplot_beta()shows the topics associated with each underlying model
Alignment can be used for (multiresolution) exploratory analysis. By highlighting topics that are robust across choices of K, it can also support evaluation of LDA models.
