The location of the cluster centers isdetermined by the pattern parameter. Three patterns are currentlysupported grid, sine and random.<br/> <br/> For more information refer to:<br/> <br/> Tian Zhang, Raghu Ramakrishnan, Miron Livny: BIRCH: An Efficient Data Clustering Method for Very Large Databases.
