A clustering method, called HACO (Hyperbox clustering with Ant Colony Optimization), is proposed for classifying unlabeled data using hyperboxes and an ant colony meta-heuristic. It acknowledges the topological information (inherently associated to classification) of the data while looking in a small search space, providing results with high precision in a short time. It is validated using artificial...
Structural relationships in data are revealed by methods of clustering and fuzzy clustering. In essence, clustering leads to the reduction of data. Dimensionality reduction comes as a complementary process in which we eliminate some features (attributes). This study introduces a concept of structure reduction which is guided by a criterion of structure retention. In particular, it is shown that each...
