%description
Reduction-based techniques for cost-sensitive multi-class classification,
in which each observation has a different cost for classifying it into one
class, and the goal is to predict the class with the minimum expected cost
for each new observation. Implements Weighted All-Pairs (Beygelzimer, A.,
Langford, J., & Zadrozny, B., 2008, <doi:10.1007/978-0-387-79361-0_1>),
Weighted One-Vs-Rest (Beygelzimer, A., Dani, V., Hayes, T., Langford, J.,
& Zadrozny, B., 2005, <https://dl.acm.org/citation.cfm?id=1102358>) and
Regression One-Vs-Rest. Works with arbitrary classifiers taking
observation weights, or with regressors. Also implements
cost-proportionate rejection sampling for working with classifiers that
don't accept observation weights.
