categoryEncodings

Simple, fast, and automatic encodings for category data using a data.table backend. Most of the methods are an implementation of "Sufficient Representation for Categorical Variables" by Johannemann, Hadad, Athey, Wager (2019) <doi:10.48550/arXiv.1908.09874>, particularly their mean, sparse principal component analysis, low rank representation, and multinomial logit encodings.
