“…Decision trees [3,4,8,29,32,38] and decision rule systems [6,7,11,12,31,32,33,34] are widely used as a means for knowledge representation, as classifiers that predict decisions for new objects, and as algorithms for solving various problems of fault diagnosis, combinatorial optimization, etc. Decision trees and rules are among the most interpretable models for classifying and representing knowledge [10,13,21,39].…”
