| Abstract(in English) | An NNC-Tree is a decision tree whose non-terminal node contains a nearest neighbor classifier. Compared with the conventional decision trees, the decision rules corresponding to NNC-Trees are more compact, more accurate, and more comprehensible. The induction of NNC-Trees, however, is relatively time-consuming. Thus, to speedup the induction process is an important issue to make NNC-Trees practically useful. To speedup the induction process of NNC-Trees, this paper proposes to reduce the dimensionality of the input space using principal components analysis before induction. Experiments on several public databases show that the proposed method is more effective than the existing algorithm when the number of features is large. |
