%description
Provides the SMOTE with Boosting (SMOTEWB) algorithm. See F. Sağlam, M. A.
Cengiz (2022) <doi:10.1016/j.eswa.2022.117023>. It is a SMOTE-based
resampling technique which creates synthetic data on the links between
nearest neighbors. SMOTEWB uses boosting weights to determine where to
generate new samples and automatically decides the number of neighbors for
eacg sample. It is robust to noise and outperforms most of the
alternatives according to Matthew Correlation Coefficient metric.
Alternative resampling methods are also available in the package.
