Abstract

In this paper

inspired by Jelonek's algorithm

an improved attributes reduction algorithm is given based on the approximation quality of a single attribute and the modified discernibility matrix due to Hu.It is shown that the presented algorithm is of lower computational complexity than Jelonek's algorithm.
