| Abstract: | According to the biggest correlation and the best interpret ability to achieve reducing dimensions based on the partial least squares. To cluster use Euclidean distance, and to obtain different information granular. Analyze the suitable granular in the actual field. It was proved to be feasible and effective after tested with a database. |
