Figure 4From: An efficient clustering algorithm for partitioning Y-short tandem repeats dataThe extreme distribution of objects A forms centroid 1 ( a 1 , a 2 , a 3 ) and centroid 2 ( a 1 , a 2 , b 3 ). In this case, the objects in Class A are equally distributed into clusters 1 and 2. Therefore, the obtained centroids are not sufficient to represent their classes.Back to article page
