%description
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 <doi:10.48550/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>.
