本文的研究任務是將空間關系進行定量化，而要將空間關系從定性到定量需要一些屬性知識和幾何知識，因而本文以人類對于空間關系的常識為出發點，為物體空間擺放區域的確定建立一些可用的知識庫，然後在知識庫的基礎上建立擺放區域的計算模型。 -
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
該演算法選擇基於質心利基於代表對象方法之間的中間策略，它不用單個質心或簇中全部對象米代表一個簇，而是選擇數據空間中定數目的只有代表性的點，這些點代表和捕捉到了簇的形狀。此外，由於引入了收縮因子使代表點向簇小心「收縮」而使該演算法能夠較好地消除孤立點的影響，在處理孤立點上也更加健壯。 -
