Research of Discernible Matrix-Based Algorithm for Attribute Value Reduction

2010 International Conference on Intelligent Computing and Cognitive Informatics, 2010
The essence and process of attribute value reduction is analyzed from the view of logic. Then a new algorithm for attribute value reduction based on rough set is proposed by constructing a discernible matrix and the correctness and feasibility is proved.

An Efficient Algorithm for Attribute Reduction Based on Discernibility Matrix

2011 International Conference on Intelligent Computation and Bio-Medical Instrumentation, 2011
A definition for reducing discernibility matrix is provided, and a reduction relative of discernibility set is analyzed to reduce the time complexity of attribute reduction algorithm based on traditional matrix. Use iterative idea to select the necessary condition attributes adding to this reduction relative. Optimize the reduction relative by complete

Discernibility Matrix Enriching and Boolean-And Algorithm for Attributes Reduction

2014
discernibility matrix and binary discernibility matrix method is easy to understand and design, which has aroused great concern by many scholar. Research shows that the two methods produce a large number of repeated and useless elements (if A is the subset of B, B is the useless element of A) on the fly. These repeated and useless elements occupy a lot

Decision Rules Extraction Strategy Based on Bit Coded Discernibility Matrix

2006
The rationality of a reduction approach for decision rules with discernibility matrix is analyzed and proved true theoretically. And a rules extraction strategy based on bit-coded discernibility matrix is presented. By bit-coding the description of discernibility matrix, the information is depicted by a series of binary code, which makes it easy to ...
