In this meetup, Rebecca Barter (http://www.rebeccabarter.com) currently a Postdoctoral Fellow at UC Berkeley gave a wonderful talk introducing tidymodels (https://www.tidymodels.org) for tidy machine learning! This is an incredibly cool topic and the tidymodels package is a very powerful tool to build and implement machine learning algorithms in R in a tidy way.
