Rough Set theory is an effective tool to deal with vagueness and uncertainty information to select the most relevant attributes for a decision system. However, to find the minimum attributes is a NP-hard problem. In this paper, we describe a method to decrease the scale of the problem by filtering core attributes, and then employ the checking tree to test the rest attributes from bottom to top by...
Data mining is hot-spot research areas recently. Based on rough set theory, this paper proposes the definition of attribute real-time and its attributes reduction algorithm. By configuring the related affect matrix of the attributes and arousing with the attributes affects, we are able to delete the redundant attributes and get the reduction set which can reflect the mutual affect among the attributes...
