There is provided a pattern separation apparatus capable of separating patterns of a specific group from a plurality of patterns constituting a plurality of groups present in an n-dimensional pattern space in accordance with simple computational processing, the apparatus being used in a variety of applications such as recognition of characters, figures, and the like. An average of a set of patterns is calculated to be Xav, and a vector closest to Xav is defined as a key point and represented by Xkey, Xkey s chosen as the most central point. An n-dimensional space having Xkey as its center is assumed to calculate a main plane in which the number of patterns is larger than that of +603 patterns. When other +603 patterns are included in the main plane, a subplane is calculated to eliminate these patterns from the main plane. When other patterns are included in planes other than the main plane, a subplane for separating these patterns from the +603 patterns and enclosing the patterns is calculated. The specific patterns are separated by the main plane and the subplanes.
