Another anomaly detection tool is the relative density. The same KNN-model that is fitted to the data with $ K=9$ is used. Furthermore, the relative density can be calculated with the following expression,
If the $\mathrm{ard} < 1$ then the specific songs is likely to be an outlier. The songs with lowest relative density score are illustrated in \ref{relden}.
