In this paper, we analyze possible number of the k Voronoi partitions of n points on the feature manifold. In information geometry[1, 2, 8], differential geometric properties of probabilistic distribution have been studied. In the fields such as language recognition or learning theory, clustering of probability distributions, called"distributional clustering"minimizing sum of Kullback-Leibler divergence plays an important role. We take geometric approach for this distributional clustering problem and extend our result in the Euclidean space. We consider k-clustering problem of n distributions by divergence in general form on the manifold with dually flat property, and the generalized primary shatter functions for this Voronoi diagram is evaluated, which directly leads to a polynomial-time exact algorithm when the number of clusters and the dimension are regarded as constants.
