  3. This algorithm adopts a middle ground between centroid - base and all - points - based approaches. instead of using a single centroid or all points to represent a cluster, a fixed number of representative points in space are chosen, these points represent and capture the geometry and shape of the cluster. in addition. the representative points of a cluster are generated by first selecting well - scattered objects for the cluster and then " shrinking " or moving them toward the cluster center by a specified fraction, or shrinking factor. the shrinking helps dampen the effects of outliers. therefore, cure is more robust to outliers
