To provide a practical perspective, we present empirical results on both real and synthetic data sets that demonstrate that this effect ca

While provably optimal and efficient algorithms exist for partitioning one-dimensional data, the multi-dimensional problem has received less attention, except for a few special c

In this paper we elaborate on the theoretical foundations
