Topological data analytic methods in machine learning rely on
vectorizations of the persistence diagrams that encode persistent
homology, as surveyed by Ali &al (2000)
<doi:10.48550/arXiv.2212.09703>. Persistent homology can be computed
using 'TDA' and 'ripserr' and vectorized using 'TDAvec'. The
Tidymodels package collection modularizes machine learning in R for
straightforward extensibility; see Kuhn & Silge (2022,
ISBN:978-1-4920-9644-3). These 'recipe' steps and 'dials' tuners make
efficient algorithms for computing and vectorizing persistence
diagrams available for Tidymodels workflows.
