Cluster networks and Bruhat-Tits buildings
- 34 Downloads
We consider a clustering procedure in the case where a family of metrics is used instead of a fixed metric. In this case, a classification network (a directed acyclic graph with nondirected cycles) is obtained instead of a classification tree. We discuss the relation to Bruhat-Tits buildings and introduce the notion of the dimension of a general cluster network.
