\title{Classification via regression wrapper.}
\usage{
makeClassificationViaRegressionWrapper(learner, predict.type = "response")
}
\arguments{
\item{learner}{(\link{Learner} | \code{character(1)})\cr
The learner.
If you pass a string the learner will be created via \link{makeLearner}.}
\item{predict.type}{(\code{character(1)})\cr
\dQuote{response} (= labels) or \dQuote{prob} (= probabilities and labels by selecting the one with maximal probability).}
}
\value{
\link{Learner}.
}
\description{
Builds regression models that predict for the positive class whether a particular example belongs to it (1) or not (-1).
Probabilities are generated by transforming the predictions with a softmax.
Inspired by WEKA's ClassificationViaRegression (http://weka.sourceforge.net/doc.dev/weka/classifiers/meta/ClassificationViaRegression.html).
