【Abstract】 The classification module in GenMiner uses the decision tree C4.5 whose time-cost is small and classification is very efficient,and which has been developed very well.The design and implementation of the classification module in GenMiner,which is a general data mining prototype system is proposed in this paper.The paper also addresses the method of decision tree C4.5 which is used in the classification module.更多还原
