Seen Multivariate Adaptive Regression Splines (MARS) in some of the tidymodels documentation and in Kuhn's books, but never really looked into them. As a model, I don't find them particularly interesting, but I'll say this, the {earth} vignettes are some of the best I've read. (not linked on CRAN page, but included w/pkg and at Milborrow's site)

@erc_bk You can also use MARS via mlr3 :-): https://mlr3extralearners.mlr-org.com/reference/mlr_learners_classif.earth.html?q=earth#dictionary
