%description
A collection of machine learning helper functions, particularly assisting
in the Exploratory Data Analysis phase. Makes heavy use of the
'data.table' package for optimal speed and memory efficiency. Highlights
include a versatile bin_data() function, sparsify() for converting a
data.table to sparse matrix format with one-hot encoding, fast evaluation
metrics, and empirical_cdf() for calculating empirical Multivariate
Cumulative Distribution Functions.
