Abstract

Abstract: Discretization is important in data preprocess.Afterresearching on the interval numbers discretization,a new algorithm is proposed.Firstly,associated degree of interval number is introduced to describethe associated relationship of two interval number,then threshold degree is defined to value discretization relationship between the datas.Finally,the algorithm defermine is applied in a group of data sets to test the performance.The experiment results compared with other discretization algorithm show that the algorithm is effective and effcient.

Key words: interval number, discretization, rough sets, associateddegree
