\section{Data Representation}

\begin{itemize}
\item The CNN produces a vector representation of the spectrograms for each audio file.
\item The EDA \cite{Ding2015451} estimates a probabilistic model from a sample to model the user profiles from the user ratings dataset and vector representation. 
\end{itemize}
