Predicting Software Maintainability using Esemble Techniques and Stacked Generalization

octubre 30 @ 10:35 am - 11:05 am

The prediction of software maintainability has emerged as an important research topic to address industry expectations for reducing costs and, in particular, maintenance costs. In the last decades, many studies have used single techniques, statistical and machine learning, to predict software maintainability but no agreement has been reached on the technique that can achieve better prediction. Ensemble techniques, which combine two or more single techniques, have been in-vestigated in recent years to take advantage of single techniques. This study in-vestigates the use of ensemble techniques (homogeneous as well as heterogene-ous) on predicting maintainability in terms of change using stacked generalization method. To this end, well-known homogenous ensembles such as Bagging, Boosting, Extra Trees, Gradient Boosting, and Random Forest are investigated first. Then the stacked generalization combination rule is used to construct heter-ogeneous ensembles by combining the most accurate homogenous ensembles per dataset. The empirical results suggest that Gradient Boosting and Extra Trees are the best homogenous ensembles in all datasets, since they were ranked first and second in all datasets, respectively. Moreover, the findings of the evaluation of heterogeneous ensembles constructed using stacked generalization showed that they gave better prediction accuracy compared to all homogenous ensembles
