The application of hierarchical reduction approach based on RST in medical diagnosing
Peng Jia-wen · Journal of Guangxi University of Technology · 2006
A hierarchical reduction approach of RST is proposed.In this approach,according to the acquisition mode,cost and the real time requirement,the attributes are classified to different parts allocated at several layers.So the knowledge in the information system can be presented hierarchically with multiple granularities at multiple layers.The application in acquiring the decision of medical diagnosing shows the validity of the hierarchical reduction apprach.
