Patent ID: 7969629

Claim:
A data classifying method for an apparatus including a processor to classify apexes of each unit hypercube on N-dimensional orthogonal coordinates where N is an integer of not smaller than 4, the method comprising: an inputting step of inputting coordinate values of the apexes into the apparatus, each coordinate value being made up of N components; a selecting step of selecting a predetermined number M of components from among the N components input in the inputting step, where M is an integer smaller than N; a computing step, performed using the processor, of computing an index value corresponding to a result obtained by adding a multiple of (M+1) based on values of respective predetermined bit positions of (N−M) components having not been selected in the selecting step, to the remainder resulting from dividing a total sum of the M components having been selected in the selecting step by (M+1); a classifying step of classifying the apexes in accordance with the index value computed in the computing step; and an outputting step of outputting a result of the classifying step.
