Granularity Transformation Operators for Granular Computing
Jiajin Huang · 2011
The triarchic theory of granular computing offers a conceptual framework of granular computing.It emphasized the exploitation of useful structures known as granular structures characterized by multilevel and multiview.The granular structures in graphs were studied,granules and levels in a graph were defined based on the vertices set,and granular structures in the graph were defined based on partial orders.Based on the granular structures in graphs,zooming-in and zooming-out operators were proposed.The zooming-in operator deals with the shift from a fine granularity to a coarse granularity and the zooming-out operator deals with the change from a coarse granularity to a fine granularity.
