<code>tidy</code> will return a data frame that contains information
regarding a recipe or operation within the recipe (when a <code>tidy</code>
method for the operation exists). See <a href="https://recipes.tidymodels.org/reference/tidy.recipe.html">recipes::tidy.recipe</a> for
more information.

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
<https://ieeexplore.ieee.org/document/4633969>. Or by decreasing the
number of majority cases using NearMiss 2003
<https://www.site.uottawa.ca/~nat/Workshop2003/jzhang.pdf> or Tomek
link removal 1976 <https://ieeexplore.ieee.org/document/4309452>.
