Attribution reduction for incomplete information systems
Yan Yan, Jian Ding, Guan Xue-zhen · Computer Engineering and Applications Journal · 2010
Essentiality of attribute exists difference.The importance of attributes for incomplete information systems is defined based on the difference degree of attributes.It’s proposed an attribute reduction algorithm based on connection degree of attri-bute weights.Finally,an illustrative example analysis shows that this algorithm can find the minimal reduction for decision table.
