%description
Imbalanced domain learning has almost exclusively focused on solving
classification tasks, where the objective is to predict cases labelled
with a rare class accurately. Such a well-defined approach for regression
tasks lacked due to two main factors. First, standard regression tasks
assume that each value is equally important to the user. Second, standard
evaluation metrics focus on assessing the performance of the model on the
most common cases. This package contains methods to tackle imbalanced
domain learning problems in regression tasks, where the objective is to
predict extreme (rare) values. The methods contained in this package are:
1) an automatic and non-parametric method to obtain such relevance
functions; 2) visualisation tools; 3) suite of evaluation measures for
optimisation/validation processes; 4) the squared-error relevance area
measure, an evaluation metric tailored for imbalanced regression tasks.
