Journal of Computer Applications
To solve the problem of choosing a best reduction from several reductions of one decision table, after thinking about the average significance of attributes in reduction and the number of attributes, a new definition named attribute significance was proposed and proved in detail. Then the algorithm of finding the best reduction was presented based on this new definition. Finally, examples demonstrate the usefulness of the algorithm.
