On the Complexity of the Problem of Choice
of Large Clusters
The paper considers the following problem. Given a set of Euclidean vectors, find several
clusters with a restriction on the maximum scatter of each cluster so that the size of the minimum
cluster would be maximum. Here the scatter is the sum of squared distances from the cluster
elements to its centroid. The NP-hardness of this problem is proved in the case where the
dimension of the space is part of the input.
