Mountain and subtractive clustering method: Improvements and generalizations

The mountain method of clustering and its relative, the subtractive clustering method, are studied here. A scheme to improve the accuracy of the prototypes obtained by the mountain method is proposed. Finally the mountain circular shell method to detect circular shells by using the mountain function is proposed. The proposed method is tested extensively on several synthetic data sets, and the results obtained are quite satisfactory. © 2000 John Wiley & Sons, Inc.
