These functions define what parameters can be tuned for specific steps.
They also define the recommended objects from the <code>dials</code> package that can
be used to generate new parameter values and other characteristics.

A dataset with an uneven number of cases in each class is
said to be unbalanced. Many models produce a subpar performance on
unbalanced datasets. A dataset can be balanced by increasing the
number of minority cases using SMOTE 2011 <arXiv:1106.1813>,
BorderlineSMOTE 2005 <doi:10.1007/11538059_91> and ADASYN 2008

number of majority cases using NearMiss 2003
