| Abstract(in English) | Mean shift, a simple iterative clustering procedure that shifts each data point to the average of data points in its neighborhood, is strongly extended in three ways. First, the window parameter controlling the size of the neighborhood is automatically determined from the original distribution of points. Second, stable, hierarchical clustering is achieved by increasing the window parameter value in a deterministic manner. Third, the guarantee of its covergence is rigorously proven. A critical comparison of the extended mean shift method to the k-means method and other hierarchical clustering methods is made using artificial 2D point distributions of overlapping Gaussians and half-circles with random noise in order to show its ability for realizing both normal decomposition and chaining effect. Moreover, the limits of the extended mean shift method's abilities are discussed by discriminating between cluster extraction and cluster representation problems. |
