[Traminer-users] groupe de séquence représentatives

[so.bellit]

Bonjour;

 L'algorithme de recherche permettant de retrouver un groupe de séqsuences reprsentative s'appuie sur une mesure de dissimilarité théorique entre deux séquences. Comment cette dissimilarité théorique est calculée? Pourriez vous m'orienter vers un article?

Bien cordialement
Sonia
