- W2389662023 abstract "The algorithm for attribute reduction based on discernibility matrix needs a lot of memory space,and many elements of discernibility matrix are not unnecessary for reduction.The efficiency of the algorithm is not good when the scale of problem is very large.For the above deficiency,an attribute reduction algorithm based on ordered discernibility set is put forward.The algorithm is not need to create the discernibility matrix and generate redundant elements,so it can cut down the storing and the computing capacity greatly,and the efficiency of the algorithm is improved.The time complexity and space complexity of the algorithm are cut down to max{O(|C|2|U/C|2),O(|C|2|MsCount|)} and O(|MsCount|).The experimental results show that the algorithm is effective and efficient." @default.
