Novel algorithm for discretization of continuous attributes based on rough sets theory

The rough set required that discretization should be maintained indiscernibility of the original decision-making system,however,many algorithms before permitted approximate quality descended controlled certain scope.This paper proposed a novel method of splitting interval.The novel algorithm was more reasonable and effective to discretization of continual attribute,and assured not to change decision-making attributes.By using C4.5 and SVM,performed the experiments respectively with the results of discreted data.The experiment results show that the presented algorithm is effective.
