1. A method comprising:
- applying, by machine logic of the computer, an inter-class filtering to a set of vector data, wherein;
the set of vector data includes a plurality of vector values from each class of a plurality of classes, andthe inter-class filtering is based, at least in part, on an inter-class distance; and
applying, by machine logic of the computer, an intra-class filtering to the set of vector data, wherein the intra-class filtering is based, at least in part, on an intra-class distance.

Abstract
Application of inter-class and intra-class filtering, based on aggregate point-to-point distances, to vector data for purposes of filtering the vector data for purposes of pattern recognition. In some embodiments: (i) the inter-class filtering is based on Euclidean distance, in all dimensions, between vector data points in vector space; and/or (ii) the intra-class filtering is based on a distance, in all dimensions, between vector data points in vector space.
