The statements about the results remain too subjective though. It lacks an objective measure of the quality of the clusters.
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 belongs to $[-1,1]$: it is
near close to $1$ if the cluster are perfectly separated to each other and
near close to $-1$ in the opposite case. However I always get values
near rather close to $0$ when I compute it to my results, 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.
A Therefore, further step would consist in developing such an index designed for this problem and to compare the results with other cluster sets generated with state-of-the-art metrics (as LCSS or DTW for example).
