\item find a way to measure how well are our cluster
\end{itemize}
I tried to use silhouette index, which is a common way to measure the quality of a clusters' set \cite{parisot:tel-00978520}.
The silhouette index belong to $[-1,1]$: it is near to $1$ if the cluster are perfectly separated to each other and near $-1$ in the opposite case. However I always get values near to $0$ applying it to my result, which does not give much information since it is a very general index, and thus there is no telling whether it suits to our problem or not.
