\title{Classification Metric}
\usage{
classification_metric(dataset, classified_dataset, unprivileged_groups, privileged_groups)
}
\arguments{
\item{dataset}{(BinaryLabelDataset) Dataset containing ground-truth labels}

\item{classified_dataset}{(BinaryLabelDataset) Dataset containing predictions}

\item{unprivileged_groups}{Unprivileged groups. List containing unprivileged protected attribute name and value of the unprivileged protected attribute.}

\item{privileged_groups}{Privileged groups. List containing privileged protected attribute name and value of the privileged protected attribute.}
}
\description{
Class for computing metrics based on two BinaryLabelDatasets. The first dataset is the original one and the second is the output of the classification transformer (or similar)
