A family of Delphi components for case-based reasoning

Abstract

Nearest neighbour (NN) algorithms are one of the more popular approaches to implementing case-based reasoning systems. A family of Delphi components are presented that implements an NN approach based on the weighted Euclidean distance (WED). To make the approach more general, the distance measure of WED is implemented by so called comparators which are specialised components for comparing attribute values.
