The hybrid music recommender approach is an implementation of feature augmentation and meta-level methods. One advantage of the meta-level method is the use of compressed users and songs information instead of sparse raw data.
%\begin{itemize}
%\item We model bananas and plums using a density estimation of the colour space.
%\item We fit a Gaussian Mixture Model using Expectation Maximization. We select the number of clusters using an MDL criteria.
%\item Typical image examples of bananas and plums look like this:
