| Abstract: | The original data that before data mining are often incomplete or abnormal.In view of this situation,on the basis of many data pretreatment algorithm,this paper presents a combination methods in data pretreatment based on genetic algorithm,which can effectively use the advantages of various methods,and improve the accuracy of the estimate.The experiments prove that this method is superior to other single methods. |
