Abstract
In this paper we review algorithmic aspects related to maximum-supportplane partitions. These partitions have been defined in Bock (1992) and analyzed in Pötzelberger and Strasser (2001). The local approach to inference leads to a certain subclass of partitions. They are obtained from quantizing the distribution of the score function. We propose a numerical method to compute these partitions B approximately, in the sense that they are asymptotically optimal for increasing sizes |B|. These findings are based on recent results on the asymptotic distribution of sets of prototypes.
