基于樸素貝葉斯和EM算法的軟件工作量缺失數(shù)據(jù)處理方法
[Abstract]:The lack of software workload data is a difficult problem in software work estimation. In this paper, based on naive Bays model and EM (expectation maximization) algorithm, a method to deal with the lack of software workload data is proposed. First of all, this paper introduces the internal mechanism of data loss, and then, this paper proposes a software workload prediction method based on naive Bays and EM algorithm. After that, this paper puts forward two methods to deal with the missing data of software workload: tolerating the missing data and repairing the missing data. Finally, the data missing processing method proposed in this paper is verified by using ISBSG and CSBSG software workload data sets. The experimental results show that the performance of the two missing data processing methods proposed in this paper is better than that of MINI repair method combined with SVM classification model, and the prediction performance of missing data repair method is better than that of tolerant data loss method. For both datasets, each category of workload data comes from a Gao Si component.
